Copper Nickel Pipe Fittings

In order to keep the pipes together safely, a pipe coupling which has coupling body and swage rings help. The coupling body consists of the main sealing tooth with an outbound sole tooth and an inbound tooth placed at the main tooth sealing. The main sealing tooth defines the first and second grooves whereas the outbound isolated tooth and the inbound tooth. These isolated teeth’s groves have enough length and depth to prevent the deforming of the pipe. The second grooves more to influence the capacity of the main sealing tooth to chew into the pipe so that a hermetic seal is provided. This also increases the coupling’s resistance quality when in tensile load.

Copper Nickel grades range between 90/10 due to 10% nickel or the ASTN B466 and ASME SB466 presence. Copper Nickel pipe fittings is mostly preferred for their moderate formability, strength, and weldability. Iron and Manganese are also included in this 90/10 alloy which gives it and extra resisting quality towards corrosion and stress cracking. Copper Nickel Pipe Fittings have key properties like less corrosion in saline water, huge resistance to stress and crevice corrosion, welding and easy fabrication, etc.A pipe fitting is designed for using coupling together which are opposed at the ends of two plastic pipes. This is done by fusion welding, i.e., the annular body of pipe fittings has a cylindrical surface inside of plastic materials. This is further covered with a cylindrical cavity to bring the opposite ends together and combine them.

Types of Copper Nickel Pipe Fittings

  • Elbow- helps in a change of direction mostly to 90 degrees and 45 degrees.
  • Coupling- connects two pipes of different sizes.
  • Union- helps in disconnecting pipes easily when you want to do repairs.
  • Reducer-permits change in pipe size to adopt in existing piping system.
  • Tee- helps in both combining and dividing the flow.
  • Cross these are four ways fittings having cross branch lines making flow easy.
  • Cap and plug- act as a cover end for pipe
  • Nipple- another short stub of pipe helps in connecting two other fittings.
  • Barb and valve help in connecting flexible hose and valves help in stop the flow regulation.

Fittingcart offers a complete range of copper nickel pipe fittings such as UNS C71500 elbow, Copper Nickel (Cu-Ni) 70/30 reducer, Copper Nickel stub ends, Copper Nickel tee, Copper-Nickel pipe bends and Copper Nickel cross. In fact, Copper-nickel is well-known for its strapping wide-ranging resistance to sea water. In debt with dignified alloy absorption, Copper-nickel (Cu-Ni) 70/30, (Cu-Ni) 90/10 pipe fittings are pervasively useful as connectors for piping system plants at ship building and power generating industries.

Applications of Copper Nickel Pipe Fittings

  • Desalination Condensers and Seawater piping
  • Power plants and Exchanger shell
  • Underwater tubing and marine hardware
  • Useful in areas of high pressure and temperatures with huge turbulence and velocity.
