Information
What are Socket Weld (SW) flanges used for?
Socket Weld Flange 1/2'' Class 300 A105 SW is manufactured according to the American ASME / ANSI B16.5 standard and is commonly specified in international piping projects. Socket weld flanges are used for industrial piping systems, pressure vessels, pumps, valves, and other process equipment.
The socket weld connection provides a strong, reliable joint that is particularly suitable for high-pressure piping systems. Welders appreciate socket weld flanges because the socket design simplifies alignment and welding.
A105 Carbon Steel
ASTM A105 is a forged carbon steel widely used for pipeline components, flanges, and threaded fittings operating at ambient and elevated temperatures. It offers excellent machinability, weldability, and mechanical strength, making it ideal for pressure applications.
Equivalent material grades: 1.0460, C22.8, P245GH, P265GH, P285GH, S235JR.
Applications
- Industrial piping
- Pressure vessels
