A105 Raised Face Socket Weld Flange
A105 Raised Face Socket Weld Flange
Item #: A105 Raised Face Socket Weld Flange
Manufacturers:
The A105 Raised Face Socket Weld Flange is a common component in piping systems. Manufactured in accordance with ASME B16.5 specifications, this flange is made from carbon steel, and is capable of withstanding hihg pressures and temperatures. The raised face design enhances the sealing surface, and its socket weld configuration allows for easy installation.
