Grades & standards
- ASTM A182
Need a dependable flange? Socket Weld Flange on MetalMitra comes in all standard face types and pressure classes to ASTM A182, ready for reliable pipe-to-pipe and pipe-to-equipment joints.
Socket Weld Flanges are designed with a socket arrangement in which the pipe is inserted into the flange and joined by welding. Their compact configuration makes them suitable for selected small-bore and high-pressure piping applications.
Socket Weld Flanges are flange components designed for welded pipe connections where the pipe is inserted into the socket of the flange before welding. They are commonly used in selected small-bore and pressure piping applications.
