Forged pipe fittings are essential components in piping systems, and they come in various types and sizes to meet different application requirements. High nickel alloys are a group of materials that have excellent resistance to corrosion, high temperatures, and various chemical environments. These materials are ideal for manufacturing forged pipe fittings that are exposed to harsh conditions and corrosive fluids.
The basic difference between a threaded union and threaded coupling is that threaded unions are made for joining and disassembling a part of a piping system such as a steam trap or control valve, etc for maintenance or replacement purpose. A coupling is used for joining pipe to pipe or pipe to a swedge. Pipe Coupling and Unions are available
