ASA 1500 Raised Face Socket Weld Flange Extra Strong A105

Built to perform under extreme pressure, the ASA 1500 Raised Face Socket Weld Flange is the high-integrity connection for industrial piping systems. Forged from ASTM A105 carbon steel, this flange is engineered to the exacting standards that critical applications in oil and gas, petrochemical, and power generation require.

The ASA 1500 pressure class rating means the flange handles some of the most intense operating conditions in the field high pressures and high temperatures environments. Its raised face design concentrates seating stress directly onto the gasket, creating a focused, leak-proof seal that holds firm. 

The socket weld configuration takes connection integrity a step further. Pipes are inserted into the socket and secured with a fillet weld, resulting in smoother internal flow, reduced turbulence, and significantly improved fatigue resistance. The extra strong wall thickness adds another layer of durability, making it well-suited for heavy-wall pipe applications. 

The flanges are manufactured to ASTM A105 standards, ensuring consistent mechanical properties, traceability, and compliance with industry codes including ASME B16.5.
