Copper Nickel 70/30 Buttweld Fittings are a type of pipe fittings designed for use in pipelines and systems where copper-nickel alloy with a composition of 70% copper and 30% nickel is required. This alloy is known for its excellent corrosion resistance in seawater and various other aggressive environments, making it suitable for marine and offshore applications, as well as in industries such as petrochemical, chemical, and power generation.
Buttweld fittings are used to connect and change the direction of pipes or tubing, and they are welded to the pipes to create a strong and leak-free joint. Copper Nickel 70/30 buttweld fittings come in various types, including elbows, tees, reducers, crosses, and caps. These fittings are typically available in a range of sizes and dimensions to accommodate different pipe diameters and system requirements.
Table Of Content
Here are some common types of Copper Nickel 70/30 buttweld fittings:
Copper Nickel 70/30 Elbows: These fittings allow changes in the direction of the pipeline and come in different angles, such as 90 degrees and 45 degrees.
Copper Nickel 70/30 Tees: Tees are used to create a T-shaped junction in the pipeline, allowing flow in three directions.
Copper Nickel 70/30 Reducers: Reducers are used to transition between pipes of different diameters to maintain proper flow and pressure in the system.
Copper Nickel 70/30 Crosses: Cross fittings are used to create a four-way junction in the pipeline, enabling flow in four different directions.
Copper Nickel 70/30 Caps: Caps are used to close off the end of a pipe or fitting, providing protection and sealing.
Copper Nickel 70/30 is known for its resistance to corrosion, biofouling, and erosion, making it a popular choice for applications involving seawater and aggressive environments. It is also valued for its excellent thermal conductivity, which is useful in heat exchange applications.
