100mm ANSI Class 150 RF Flange – Socket Weld x NPT, ASTM A105 Carbon Steel

This 100mm ANSI Class 150 Raised Face (RF) Flange combines a Socket Weld connection on one end with a threaded NPT outlet, offering flexibility and secure integration into a wide range of industrial piping systems. Manufactured from ASTM A105 forged carbon steel, it is ideal for high-temperature and high-pressure applications in oil & gas, petrochemical, power generation, and general industrial environments.

The flange's precision-machined raised face ensures proper gasket alignment and reliable sealing performance, while the dual connection options simplify assembly and reduce welding time in the field.
