Product Description

Standard of copper-nickel flange
Copper nickel flange is a kind of flange connector used in ships, ocean engineering, petrochemical and other fields, and its material has good marine corrosion resistance and strength. At present, the standards of copper nickel flanges are mainly American standards, European standards, British standards, etc., of which the American standards mainly include ANSI, ASME, API, etc., and the European standards mainly include EN, DIN and so on. Within these standards, we produce plate flange, staineless steel flange, anticorrosion flange, forged orifice flange, weld neck flange, blank flange, blind flange and so on.

Second, copper nickel flange specifications and manufacturing
Copper-nickel flange specifications are divided into American and metric two kinds, commonly used size 1/2"-48". The manufacturing process mainly includes forging, machining, welding, inspection, etc. The manufacturing process requires strict requirements to ensure the strength and sealing performance of copper nickel flanges.

Third, the advantages and disadvantages of copper nickel flange
Copper nickel flange including copper nickel plat flange, copper nickel threaded flange, copper nickel screwed flange and so on, has good corrosion resistance and high strength and other advantages, suitable for use in the marine environment. However, there are also some defects, such as copper nickel flange manufacturing process is complex compare to stainless steel flange

Fourth, the application of copper nickel flange
Copper nickel flanges are widely used in ships, marine engineering, petrochemical and other fields, such as pipelines, valves, pumps and other equipment connections. In the use of copper nickel flanges, should also pay attention to its use of temperature range, material forging state, fastening torque and other factors.
