The Copper Nickel 90-10 Socketweld Flange (SWRF) is a high-performance pipe fitting designed for secure, leak-proof connections in piping systems. Made from a copper-nickel alloy containing 90% copper and 10% nickel, it offers excellent resistance to corrosion, especially from seawater, brine, and other aggressive environments. The socketweld design allows the pipe to be inserted and welded at the flange, providing a strong, permanent joint suitable for high-pressure applications. Ideal for marine engineering, offshore platforms, desalination plants, and chemical processing, the 90-10 copper-nickel socketweld flange delivers durability, reliability, and long service life in demanding industrial and marine conditions.

The Copper Nickel 70-30 Socket Weld Flange (SWRF) is a durable piping component designed for high-corrosion resistance in marine, seawater, and chemical industries. Made from 70% copper and 30% nickel, it offers excellent protection against pitting, erosion, and biofouling. The socket weld design allows the pipe to be inserted into the flange socket and welded around the joint, ensuring a strong, leak-proof connection capable of withstanding high pressure and temperature. This flange combines reliability, longevity, and ease of installation, making it ideal for critical piping systems in harsh environments, including offshore, shipbuilding, and chemical processing applications.

The Copper Nickel 70-30 Eccentric Reducer is a corrosion-resistant piping component used to connect pipes of different diameters in seawater, marine, and chemical applications. Comprising 70% copper and 30% nickel, it provides excellent resistance to pitting, erosion, and biofouling. Its eccentric design ensures a smooth flow transition while preventing air pockets in horizontal piping systems. Ideal for high-pressure and high-temperature environments, this reducer offers durability, reliability, and ease of installation. It is widely used in offshore, shipbuilding, and chemical processing pipelines, ensuring efficient, long-lasting, and corrosion-resistant fluid management.
