Shihang maintains a broad inventory of Copper Nickel Flange C70600 (90/10) and C71500 (70/30) flanges. Copper Nickel has proven to be very resistant to seawater, brine water, organic compounds, salts, diluted non-oxidizing acids, and more. Due to a high resistance towards marine organisms such as barnacles, Copper Nickel is commonly used in seawater piping systems and oil piping systems

Composite Weld Neck Flange Weights & Dimension

composite weld neck flanges is made of inner flange , also called collar & backing flange (loose flange).The collar is butt welded with copper nickel pipes , the backing flange can be active. Collar is the sealing surface, the role of the backing flange is to press them. Because of collar is blocked, backing flange does not contact with the media. This flange connections are applied, in low-pressure and non critical applications, and is a cheap method of flanging , normally used in shipment.

Composite Slip On Flange Weights & Dimension

composite slip on flanges is made of inner flange , also called collar & backing flange (loose flange).The collar is welded with copper nickel pipes like slip on flanges, the backing flange can be active. Collar is the sealing surface, the role of the backing flange is to press them. Because of collar is blocked, backing flange does not contact with the media. This flange connections are applied, in low-pressure and non critical applications, and is a cheap method of flanging , normally used in shipment.

Copper Nickel Weld Neck Flange Weights & Dimension

These pipe flanges attach by welding the pipe to the neck of the flange. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Weld neck flanges are often used for applications where high pressure is a factor. The inside diameter of the flange is designed to match the pipe’s inside diameter. Weld Neck Pipe flanges with a hub have published specifications that range from 1/2″ thru 24″.

Copper Nickel Solid Slip On Flange Weights & Dimension

Slip-on plate pipe flange actually slip over the pipe. The pipe flanges are typically made with an inside diameter of  the pipe flange slightly larger than the outside diameter of the pipe. This allows the flange to slip over the pipe  but to still have a somewhat snug fit. Slip-on pipe flanges are secured to the pipe with a fillet weld at the top and  the bottom of the slip-on pipe flanges. These pipe flanges are also further catagorized as a ring.

Copper Nickel  Socket Weld Flange Weight & Dimension

Copper Nickel Socket Weld flanges were initially developed for use on small-size high pressure piping. Their static strength is equal to Slip On flanges, but their fatigue strength 50% greater than double-welded Slip On flanges.

The connection with the pipe is done with one fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.

Copper Nickel Threaded Flange Weight & Dimension

Copper Nickel threaded flange is the flange of the hole into the pipe thread, and with a threaded pipe supporting the realization of the connection, it is a non-welded flange. Compared with butt weld flange , slip on flange and socket weld flange ,the installation of threaded flange is easier ,it can be allowed to use in some of non-welding pipe line. The most common threaded type is bspt & npt .However, it is advisable not to use threaded flanges in the event of a sudden change in pipe temperature or a temperature above 260 ° C below -45 ° C to avoid leakage.

Copper Nickel Blind Flange Weights & Dimension

Copper nickel blind flange ,  the middle of the flange without a hole, it is used for sealing the pipe plug. Normally the face type in copper nickel fiedl is raised face. these flanges are suitable for higher pressure temperature applications.

Application of Cupro Nickel Flanges

Because of the specific copper nickel properties, this alloy of copper is used in different industries that include:

  • Shipbuilding and repair
  • Desalination plants
  • Offshore oil and gas platforms and processing and FPSO vessels
  • Power generation
  • Seawater system design
  • Seawater system components
  • Hulls of boats and ships
  • Armanents industry

Cupro Nickel is extremely resistant to corrosion in the water for the reason that the electrode potential of it has been adjusted to become neutral in connection with seawater. In this reason, copper nickel is used for heat exchangers, piping and condensers in the seawater systems.
