    Let’s go straight to the main subject of this guide:

     

    Chapter 1 : Copper Nickel Pipes Specifications

     

    Copper nickel pipe specifications are yet another important aspect I want you to know.

    So, for this section, I am going to discuss 5 important things to consider when buying copper nickel pipes.

    With this information, you can easily buy a cupro nickel pipe that meets the specific needs of your applications.

    So, let’s go straight to the main subject of this section:

     

     

    • Copper Nickel Pipes Specifications are ASME B36.19 M | DIN 86019 | EEMUA 144 | MIL-T-16420
    • Copper Nickel Pipes dimensions include ½ inches to 24 inches NB and OD in distinctive thickness
    • Length is 6 meter or your required length ( no longer than 6 meter )
    • Type is Seamless | Welded

    From OD 16 to OD 419 , the copper nickel pipe type is seamless.

    From OD 457 or more , the copper nickel pipe type is welded.

    • Ends are Plain | Beveled.

    Normally , the copper nickel pipe end is plain , if you require beveled , it’s available.

    • Grades of Copper Nickel are Cupro Nickel C71500 (70/30) | Cupro Nickel: C70600 (90/10).

    For now, cuni 90/10 is more common than cuni 70/30. Because cuni 90/10 is more cheaper and easy to machine.

    • Available in different sizes.
    • Copper nickel pipe pressure rating:
    DIN86019PN10 , PN14
    EEMUA 14414BAR,16BAR
    ASME B36.10MSCH5,SCH10,SCH40,SCH80
    MIL-T-16420CLASS 200,CLASS 500

     

    Copper Nickel Standard Specifications

     

    Normally, these standards form the benchmark for manufacturing copper nickel pipes for all applications. It doesn’t matter whether you want a copper nickel pipe for marine or non-marine applications.

    I know there are many copper nickel standard specifications out there. However, for the scope of this section, I will focus on three main dimensional standards.

    They include:

    Whenever you’re evaluating copper, nickel pipes based on these standard specifications, your main focus should be on outside diameter, wall thickness, weight, pressure rating and of course the type of material.

    Let me give you an example to understand what I am talking about:

     

    U.S. Standards for cupper nickel pipes

    U.S. Standards for cupper nickel pipes

     

    In short:

    You must state the dimensional standard for copper nickel pipe.

    Copper Nickel Pipe Size Chart

     

    shihang cupro nickel pipes

     

    As you can see from section (1.1) above, you already have an idea of the size of copper nickel pipe.

    So here, I will make it straightforward for you to understand.

    The copper nickel pipe size will vary depending on the dimensional specification, as I have highlighted above.

    From here you will know:

    • Copper nickel pipe length; they are normally 6 meters or less
    • Copper nickel pipe outer diameter
    • Copper nickel wall thickness

    You can check the copper nickel pipe wall thickness chart  , copper nickel pipe weight as below.

    Different copper nickel pipe pressure rate , different copper nickel pipe thickness.

    The higher copper nickel pipe pressure rating , the thicker copper nickel pipe wall thickness is.

     Cupro Nickel Pipe End Design

     

    It basically refers to the design of the pipe. Here, you can choose from the following three options:

    • Copper nickel pipe with a plain end

     

    Copper nickel pipe with a plain end

    Copper nickel pipe with a plain end

     

    • Copper nickel pipe with a threaded end

    Cupro Nickel Pipe with a beveled end

     

    As a general rule, all these will depend on where you intend to install the copper nickel pipe systems.

    But, even before I proceed to the next classification criteria, I want to mention this:

    Depending on the copper nickel pipe manufacturing process, you may go for

    • Seamless copper nickel pipes
    • Welded copper nickel pipes

    Let me tell you the truth:

    This is an important classification criteria when buying copper nickel pipe. It’s for this reason that I have a comprehensive video for you about this subject.

    It won’t take much of your time – this is a 9 minute video (spare that to be an expert)

    Good, having said that, let’s move on to yet another important aspect.

     

    Copper Nickel Pipe Pressure Rating

     

    Again, I will refer you to the table and standard specifications I highlighted in section (4.1) of this chapter.

    Still, I will make a quick overview here:

    The pressure rating of nickel pipes depends on the dimensional standard specification. For instance, we have the following:

    • DIN 86019 pressure rating: 10bar, 14bar
    • EEMUA 144: 16bar, 20bar
    • ASME B36.19M: Sch 5s, Sch10s, Sch 40s, Sch 80s
    • MIL-T-16420K: Class 200, Class 700

    The bottom line:

    Whenever you’re buying a copper nickel pipe, please specify the dimensional standard.

     

    Cupro Nickel Pipe Grade

     

    It is important to note that the main copper nickel grades you can consider are:

    • Copper Nickel 90/10 (C70600)
    • Cupro Nickel 70/30 (C71500))

    In a nutshell, you must specify the type of copper nickel pipe you want to buy based on the key parameters I have mentioned above.

    I will show you the copper nickel 90/10 & cupro nickel 70/30 chemical composition and physical properties at below section.

    Chapter 2 : Machining and Fabricating Copper Nickel Pipes

    The truth is that copper-nickel alloy pipes come in a wide range of product fittings and forms. One of the significant property of this alloy is its ductility.

    This feature makes it rather easy to fabricate this alloy. You’ll also notice that copper-nickel tubing can be expanded much easier into tube sheets.

    Definitely, this also makes it necessary to allow for easy manufacturing of shell and tube heat exchangers.

    In this section, we want to find out various aspects revolving around manufacturing, fabricating, cutting, threading and welding of copper-nickel alloy pipes.

    Make sure that you stay here to understand more;

     

    Copper Nickel Pipe Manufacturing Process

     

    Many people hardly have an idea of how copper nickel pipe is manufactured. Clearly, it is understandable because most people often have an interest in the end product.

    But don’t you think having a general idea of the manufacturing process of this product would be necessary?

    I think it would.

     

    Copper nickel pipes

    Copper nickel pipes

     

    Let me take you through how it happens.

    So that next time you’re making your order, at the very least, you’d understand a few elements regarding the process it undergoes during manufacturing.

    The funny bit of this product is that it works so well but trust me the making process isn’t necessarily hi-tech.

    But the good thing, all the same, is that the ultimate product meets the strict quality specifications.

    Now continue reading on to get an idea of the production process of this product;

    1.      Raw materials

    The process logically starts with raw materials which in this case is copper. This raw material may be ingots, refined or just scrap copper.

    The choice in this case, however, is dependent on some elements such as availability, cost as well technical capabilities of the plant to furnace the material.

    Don’t worry about this I will explain it in just a bit.

     

    Copper Nickel Ingots

    Copper Nickel Ingots

     

    But you also need to bear it in mind that at times the quality of end product is often defined by the type of raw material that you used.

    In this case, therefore, refined copper will certainly produce a relatively higher quality copper nickel pipes than the copper scrap raw materials.

    2.      Melting

    Now at this point, the raw materials are placed in the melting furnace. It is primarily a sizeable tube mill with a capacity that ranges up to 20 tons.

    The essence of this chamber is to melt the raw materials, specifically the ingots and scrap. It is not by any standards ideal for melting refined copper.

     

    Otto Junker Furnace

    Otto Junker Furnace

     

    It’s incredible because imagine the melting temperatures go up to 2400 degrees Fahrenheit. Ordinarily, that’s extremely hot.

    While still hot, it is refined by contacting it with oxygen with the intention of reacting with impurities in a bid of forming oxides.

    But since the oxides are comparatively lighter than liquid metal, they tend to float on the surface and trapped inside slag.

    At this point, all impurities need to be eliminated. Some can however on be removed by using specific compound slag to react them with.

    Evaluation and transfer of samples take place as means of monitoring the impurity content. The purity level must conform to the ASTM specification which then allows it to proceed to casting.

    3.      Casting

    Casting starts in a tundish. During this time, the molten metal is heated moderately to maintain its temperature.

    The molten metal is as well covered using a blanket that contains graphite powder as a way of preventing oxidation.

    Afterward, the molten metal is cast into comparatively large logs by using either of these methods, continuous or semi-continuous.

    In some instances, however, the casting mold has a central core for cool water. Therefore, it allows the log to emerge as a thick-walled pipe known as tube round.

    4.      Piercing

    This is the next step in the manufacturing process of copper-nickel alloy pipe. Piercing comes after casting, and it necessarily involves reheating the billets to 1535°F or thereabouts.

    The essence of this reheating is to make this metal pliable.  A sharp pointed rod of similar length and desirable size is also known as the piercing mandrel is then forced through the center of the billets.

     

    Mandrel mill in cupper nickel pipe manufacturing process – Image source-WERMEC

    Mandrel mill in cupper nickel pipe manufacturing process – Image source-WERMEC

     

    This leads to the creation of internal walls of the Cu Ni alloy pipe. Still, you also need to take note that this process is unnecessary especially if, during casting, the billets were molded as tube rounds.

    Moreover, it’s also imperative to know that piercing can happen before extrusion or can take place simultaneously with extrusion.

    5.      Extrusion

    Let me give a simple analogy of understanding extrusion process:

    You see when you’re holding your toothpaste tube and trying to squeeze it to remove the paste, that’s how extrusion of this metal occurs. Yes, it is more or less a similar process.

    So during extrusion, you’ll find that the billet heats accordingly to meet the standards of hot-working temperatures. After that, it is placed in a chamber which contains an extrusion press.

    The molten metal is forced over the mandrel and then through the hole which is inside the die. The result is the formation of a hollow tube spurting out of the extrusion press in a similar way that the toothpaste squirts out of the tube.

     

    Extrusion process

    Extrusion process

     

    What follows is that the metal which is closer to the billet’s surface extrudes backward and forms a shell.

    Copper oxide is present in this shell hence need for removing and refining it in the refining furnace.

    Rollers then carry the extruded tube that emerges from die on a flat long table to make it straight to the level is cool enough to handle.

    The tube is then eventually cleaned to allow for removal of surface oxide scale as means of preparing it to a subsequent stage in pipe making process.

    6.      Drawing

    This stage primarily involves pulling the hollow tube through a sequence of toughened steel dies to decrease the diameter accordingly.

    Prior to every step of this process, the pipe is pointed at one end to make it possible for it to fit through when placed in the next die.

     

    Drawing process

    Drawing process – Image source: Tech Miny

     

    The die and mandrel perform together as a way of reducing both the diameter and wall thickness of the pipe.

    The pipe is drawn in numerous stages until the moment that the ideal wall thickness and diameter is achieved.

    The drawing work generally toughens the copper allowing the pipe to be reasonably stiff.

     

    Cutting Cupro Nickel Pipes

     

    We have several ways for cutting the copper-nickel pipes. In fact, several typical cutting procedures are acceptable when dealing with copper nickel pipes.

    For instance, shearing, plasma arc, and abrasive disc cutting are all acceptable for Cu Ni pipes. Nevertheless, abrasive water jets are cutting, and laser might as well be considered.

    Pro Advice:

    You can use shears and band saws. However, you must ensure that you leave some allowance. It is because alloys tend to be somewhat soft and ductile.

    Another tip is that never use oxy-acetylene cutting for copper-nickel alloy pipes.

     

    Cutting copper nickel pipes

    Cutting copper nickel pipes

     

    In general, cutting copper nickel pipes is easy but only when you’re using the right cutting methods.

     

    Threading Copper Nickel Pipes

     

    One of the most fundamental aspects regarding threading is selecting the ideal drill size. And again, it is imperative to understand that this is one action that involves a lot of friction.

    So possibly, the threading machine has to have a pump oil at work. Alternatively, you have to ensure that you flood the tool nose with sulfurized oil during this process.

     

    Copper Nickel Pipe with threads

    Pipe with threads

     

    The depth of the threading cut has to vary depending on the thickness of the copper-nickel pipe.

    Nonetheless, the treading dies have to be sharp and flooded with a soluble oil, cutting fluid or any rich chemical solution when using it.

    To produce V-threads, the ideal chamfer angle should be in a range of 15 to 20°.

    You also need to have it in mind that external thread can be produced on copper-nickel alloy pipe by form grinding.

    Seamless pipe inspection entails performing a chemical component test, mechanical properties test, visual inspection, and hydrostatic test.

    • Chemical component test

    To determine if seamless copper nickel pipes are ideal for the intended application, they are subjected to a chemical component test.

    Chemical component test is aimed at confirming that the copper nickel pipes meet the specified chemical requirements depending on the material standard.

    This test is conducted at both macro and micro levels.

    Macro test inspection entails analyzing the raw material and the final products to ensure that the alloy elements are within the specified range.

    Macro test analysis entails checking copper nickel pipes to ensure proper fusion with the intended use or application.

    • Mechanical properties test

    Mechanical properties tests entail inspecting the copper nickel pipe.

    It ensure that it conforms to the required mechanical standards as per the specified standards of the material.

    A sample is taken from the pipe and used to perform the test.

    This test entails examining the integrity, temperature effect, impact resistance, and tensile strength of the material of the pipe.

    Essentially, this inspection is aimed at ensuring that the final product meets the required mechanical standards.

    • Visual inspection

    Visual inspection of copper nickel pipe is used to check the overall quality of the product.

    During this inspection, the inspection engineers check the overall finish of the product.

    They check the surface of the pipe for imperfections that may include tears, mechanical marks and other forms of visible imperfections.

    They also check defects like undercuts, porosity, under or excess fill of the material, and unevenness.

    The accepted visual imperfections are specified in the ASTM copper nickel pipe standards.

    Chapter 9: How BanSar Ship the Copper-Nickel Pipe from China by Sea

     

    Well, you’ve realized what it takes to buy copper nickel pipes and appropriate ways of determining an ideal manufacturer of the same.

    So you send your order, it’s approved, and now it’s time for shipping them to your destination.

    Shihang, of course, is a Chinese-based company. And you’re probably wondering the best way possible for your goods to get home.

    Moreover, it’s your first time to make such an order and start pondering of the means of getting them at your place.

    Listen, this is an easy task. In fact, how to ship them from China to your respective place should be least of your worries.

    You know why?

    Because you always have best shipping partner just a click away from your internet browser.

    And this partner is BanSar China Shipping and Logistics Company.

    In this section, I will show you how BanSar ensures you get all copper nickel pipes and accessories in any part of the world.

    Let’s get to that:

    1.      Pick up the Copper Nickel Pipes from Shihang

    Once you’ve made your order, it is upon the respective department within Shihang to ensure that it receives and works on it.

     

    Copper Nickel Pipe Stock

    Copper Nickel Pipe Stock

     

    Fundamentally, the officials have to make sure that they pick all the ordered pipes and assemble them accordingly.

    All these orders are picked from the stock, which contains all types of copper-nickel pipes that you would wish to get.

    Once this process is over, the ordered pipes get to the next stage.

    2.      Printing Copper Nickel Pipes

    At this stage, what happens is that the pipes are taken to labeling machines for printing. Printing, in this case, involves elements such as size, length, thickness, and weight of the pipe.

    Printing also contains information about the type of copper-nickel alloy used as well as other standard specification details.

     

    Printing copper nickel pipes

    Maybe you’d be asking the essence of printing the pipes when you order them.

    Here’s the truth:

    Printing helps in sorting the tubes according to different features.

    So that it becomes relatively easy for you to select and use them appropriately depending on the type, size, thickness, and length of the pipe.

    It is also vital because it reduces time wasting and confusion upon receiving the consignment and trying to find out which one goes where.

    3.      Put Copper Nickel Pipes into the Seaworthy Wooden Case

    Once labeling is done, the next process is packaging. Now, this is one of the most critical aspects that is given substantial consideration.

    It is of course of great significance because understandably, BanSar will be shipping the pipes by sea. So most probably, depending on distance, it might take quite long to get to your destination.

    And that is the reason packaging needs to be intensive to guarantee the safety of the shipment before, during and after offloading.

     

    Putting copper nickel pipes into the wooden case

    Putting copper nickel pipes into the wooden case

     

    The wooden case provides the best material for packing and transporting these copper-nickel items.

    You can be sure of getting these pipes safe and sound as soon as they arrive at your destination.

    1.      Finish the Packaging Copper Nickel Pipes

    Once assorting and packing of the pipes inside the wooden cases is over, the case is then enclosed.

    This serves two principal purposes; one is that it enhances the security of these pipes such that it becomes difficult to remove even a single piece before you get them.

    It is vital since it helps in preventing any cases of loss of a pipe or interference with the consignment during transit.

     

    Finish Packaging Copper Nickel Pipes

    Secondly, the case sealing makes it easy for transportation of the consignment at all levels.

    To mean that it is easy to load it on a truck, train, or even ship when the casing is entirely sealed than otherwise.

    Nonetheless, complete sealing of the wooden case also serves in ensuring that the pipes are not exposed to other external elements.

    It is necessary since some of these elements would probably affect or impair them before getting the items.

    2.      Transport Copper Nickel Pipes by Trucks

    So the moment packaging is over, the next step is finding a way of transporting the goods to the seaport.

    You see, Shihang is located relatively far away from the port. And thus there is a need for transporting the packaged items to the port for sea shipping.

    So the best means, in this case, is loading the cargo on a truck and transporting them by road to the port.

     

    Transporting copper nickel pipes by truck

    At this point, BanSar has carried out all the preliminary assessments regarding shipping and has obtained all the necessary documents to ease the movement of these pipes.

    It is important because it also reduces time wasting at the customs and other related offices that would hinder or delay shipping process of this item.

    3.      Loading Copper Nickel Pipes Into the 40GP Container

    This is where the wooden cases that contain the copper-nickel pipes are now loaded into the containers awaiting custom clearance and subsequent ocean freight to the respective destinations.

    Most of the pipes are often 6 meters long, and the wooden case has a length of 6.08 meters; slightly longer than the pipes. Thus they fit well in such cases.

     

    loading copper nickel pipes in a container

    loading copper nickel pipes in a container

     

    But then, with the length of 6.08m, it means that the wooden cases can only load into a 40GP container and not necessarily 20GP container.

    So it important to take note of that fact in as much as all these are handled by BanSar China.

    Once every aspect regarding port clearance at the customs and any other is done, BanSar finds the right shipping carriers to transport the consignment to your destination.

    All these time, BanSar allows you to track your cargo to know its status if there’s need to. And the process continues until the moment you receive your copper nickel pipes.

    If you could be interested, BanSar might as well help in clearing this cargo at your home port and facilitate transport especially if you’re living in a landlocked country.

    Basically, BanSar is a trusted shipping partner that facilitates shipping of your copper nickel pipes by sea from Shihang copper nickel pipe manufacturer.

    So next time you think of shipping your pipe from China, just think BanSar.

    Conclusion

    As you’ve seen, finding the best copper nickel pipe manufacturer in China involves much more than just buying the pipes.

    You need to look into several aspects to make it easy for you to get the best quality and desirable efficiency.

    I’m hopeful that through this guide, you’ve learned quite a lot of things concerning copper-nickel alloy pipes.

    Copper Nickel Pipe Specifications – ASME B36.19M

    Shihang, one of the world class copper nickel pipe suppliers and manufacturer in china.

    We have a wide range stock of copper nickel pipe as per ASME B36.19M Standard.

    1.Scope

    ASME B36.19M Standard covers the standardization of dimensions of welded and seamless wrought copper nickel pipe for high or low temperatures and copper nickel pipe pressure ratings. The word copper nickel pipe is used, as distinguished from copper nickel tube, to apply to tubular products of dimensions commonly used for pipeline and piping systems.

    Copper nickel pipes NPS 12 (DN 300) and smaller have outside diameters numerically larger than their corresponding sizes. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes.

    The wall thicknesses for NPS 14 through 22, inclusive (DN 350–550, inclusive), of Copper nickel pipe schedule  10S; NPS 12 (DN 300) of Copper nickel pipe schedule  40S; and NPS 10 and 12 (DN 250 and 300) of Copper nickel pipe schedule  80S are not the same as those of ASME B36.10M.

    The suffix “S” in the copper nickel pipe schedule  number is used to differentiate B36.19M copper nickel pipe from B36.10M copper nickel pipe. ASME B36.10M includes other copper nickel pipe thicknesses that are also commercially available with copper nickel material.

    2 Copper Nickel Wall Thickness Chart

    The size of all copper nickel pipe in copper nickel pipe Table 1 is identified by the nominal copper nickel pipe schedule , copper nickel pipe wall thickness and copper nickel pipe dimensions , copper nickel pipe pressure rating.

    The manufacture of copper nickel pipe NPS 1⁄8 (DN 6) through NPS 12 (DN 300), inclusive, is based on a standardized outside diameter (OD). This OD was originally selected so that copper nickel pipe with a standard OD and having a wall thickness that was typical of the period would have an inside diameter (ID) approximately equal to the nominal size.

    Although there is no such relation between the existing standard thicknesses — OD and nominal size — these nominal sizes and standard ODs continue in use as “standard.”

    The manufacture of copper nickel pipe NPS 14 (DN 350) and larger proceeds on the basis of an OD corresponding to the nominal size.

    Weight = 0.028*(D − t)*t

    Wight in KG

    D = outside diameter in mm

    t= wall thickness in mm

     

    5 Permissible Variations

    Variations in dimensions differ depending upon the method of manufacture employed in making the copper nickel pipe to the various specifications available. Permissible variations for dimensions are indicated in each specification.

    6 Copper Nickel Pipe  Wall Thickness Selection

    When the selection of copper nickel pipe wall thickness depends primarily upon capacity to resist internal copper nickel pipe pressure rating under given conditions, the designer shall compute the exact value of copper nickel pipe wall thickness suitable for conditions for which the copper nickel pipe is required, as prescribed in detail in the ASME Boiler and Copper nickel pipe pressure rating Vessel Code, ASME B31 Code for Copper nickel pipe pressure rating Piping, or other similar code, whichever governs the construction. A thickness shall be selected from the copper nickel pipe schedule s of nominal thickness contained in Table 1 to suit the value computed to fulfill the conditions for which the copper nickel pipe is desired.

    Question / Answer

    What Is Copper Nickel Pipe?

    Copper nickel pipe is a straight, pressure-tight, cylindrical hollow that is made of copper and nickel alloy and used in different piping systems.

    Copper nickel pipe has been used in seawater piping and marine engineering as well as gas and oil market applications for years.

    Copper is a noble metal with an excellent corrosion resistance in fresh water and general atmosphere.

    Nickel is a common element in many metal alloys.

    It enhances resistance to both oxidation and corrosion.

    Additionally, it adds durability and strength when combined with other metals both in low and high temperatures.

    The most common copper nickel alloys are 90/10 and 70/30.

    Copper nickel 90/10 is the most common due to its high corrosion resistance, strength, and resistance to prevalent biofouling in salt water environments.

    However, copper nickel 70/30 is stronger than the most common copper nickel 90/10.

    It’s also capable of withstanding corrosion in higher velocities.

    CuNi 90/10 alloy is commonly used in most marine applications.

    What Is Copper Nickel Pipe Working Principle?

    Copper nickel pipes work with copper nickel pipe fittings and copper nickel flanges to form a strong copper nickel pipe system.

    You can easily get items like flanges, copper nickel elbows, copper nickel tees, copper nickel reducers, forged and machined fittings.

    Then welding copper nickel pipe with all others fittings and flanges to be a copper nickel pipe system.

    Essentially, it’s possible to have standard products and items that are made to suit your specific piping design. These items are available in both 70 30 copper nickel pipe and 90 10 copper nickel grades.

    You can get more info about copper nickel pipeline system at our blog page.

    Main Standard Of Copper Nickel Pipes

    The standard of every copper nickel pipe depends on the application for which it is made. For instance, standard seamless copper nickel pipe that comes with a straight length is ideal for general engineering applications. Each copper nickel pipe is made from billets by piercing or hot extrusion then subjected to cold annealing and working.

    Main standard specifications for copper nickel pipes include:

    There are four main pipe standards for copper nickel pipes. You can check the copper nickel pipe size chart, cuni pipe dimension, and copper nickel pipe weight chart below:

    • DIN 86019:SEAMLESS TUBES MADE OF CUNI10FE1,6MN FOR PIPES
    • EEMUA 144
    • ASME B36.19M
    • MIL-T-16420K:MILITARY SPECIFICATION: TUBE, COPPER-NICKEL ALLOY, SEAMLESS AND WELDED
    What is Copper Nickel Pipe Chemical Component ?

    Copper nickel pipe has properties that make it useful in different applications.

    Chemical properties

    Copper nickel pipe is made of copper and nickel just like the name suggests. However, the copper nickel alloy that is used to make this pipe has other strengthening elements. These include manganese and iron. Nevertheless, copper amount is usually higher though the alloy has a silver color. The chemical composition of copper nickel pipe gives it both chemical and physical properties.

    What is Copper Nickel Pipe Physical Properties?

    Physical properties

    Major physical properties of copper nickel pipe include:

    • Corrosion resistance- This pipe does not get tarnished. That’s because a complex surface film forms on this pipe through the interaction of the alloy with seawater. This protects the pipe from corrosion thereby enhancing its durability.
    • Biofouling- Copper nickel pipe is resistant to biofouling. That means it lowers macro-fouling levels when used in marine applications. This property is attributed to the formation of a complex protective film on the surface of the copper nickel pipe.
    • Excellent ductility and tensile strength- Hardness and high tensile strength are achieved by making the pipe from cold worked copper nickel alloy. Nevertheless, nickel addition to copper generally improves durability and strength of an alloy.
    • Aesthetically pleasing colors- The color of this pipe becomes lighter with nickel addition. A pipe that is made of low-nickel alloy has a yellow-pink hue. Pipes whose making alloy has more than 15% nickel look silvery-white. When inside the seawater, the pipe can turn into different colors including green, dark brown, and golden brown.
    • Anti-microbial- Copper nickel pipe is inherently anti-microbial. When the surface of this pipe is cleaned regularly, it kills bacteria that may cause infections continuously.
    • Environmental friendly- Once a copper-nickel pipe has formed a complex protective film on the surface, the amount of the copper that is released into the environment or water is greatly reduced. Additionally, the pipe releases copper ions close to the formed protective film. These ions inhibit slime layer’s growth making the surface of the pipes uninviting to marine macro-organisms.
