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.

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. That’s why it 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.

    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.
    How to Do Inspection for Copper Nickel Pipe?

    Copper nickel pipe inspection

    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 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 to 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.
