Introduction Copper-nickel alloys have been widely recognized for their superior resistance to corrosion, high durability, and excellent mechanical properties. Among the most popular grades, C70600 (CuNi 90/10) stands out due to its excellent performance in marine, offshore, and industrial applications. Copper-nickel fittings, such as Weldolet, Sockolet, and Threadolet, play a crucial role in creating robust and efficient piping systems. Designed to withstand high pressures and extreme environments, these fittings are indispensable in industries that demand reliability and longevity.
Understanding Copper-Nickel C70600 (CuNi 90/10) Fittings C70600, commonly known as CuNi 90/10, is composed of 90% copper and 10% nickel, along with small amounts of iron and manganese to enhance its corrosion resistance. This alloy is widely used in seawater and industrial applications due to its ability to resist biofouling, stress corrosion, and high temperatures. Fittings made from CuNi 90/10 ensure superior performance, making them ideal for shipbuilding, offshore structures, desalination plants, and chemical industries.
Types of Copper-Nickel Outlet Fittings Outlet fittings are specialized pipe fittings that allow for a smooth transition between main pipes and branch connections. Some of the most widely used outlet fittings include:
Weldolet:
A butt-weld branch connection used to reinforce piping systems.
Distributes stress efficiently, making it a preferred choice for high-pressure applications.
Ensures a smooth flow of fluid, minimizing turbulence and pressure loss.
Sockolet:
Features a socket-weld connection, providing a leak-proof and secure fit.
Best suited for smaller diameter pipes with high-pressure ratings.
Enhances the integrity of the piping system by reducing welding efforts.
Threadolet:
A threaded outlet fitting used in low-pressure systems where welding is not feasible.
Enables quick installation and easy maintenance.
Commonly used in utility pipelines, instrumentation systems, and industrial plants.
