Socket weld pipe flanges are used in the applications where there are smaller sizes of high pressure pipes used. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This helps in better flowing of the fluid or gas inside the pipe. These socket weld pipe flange is available in all materials, sizes and specifications.

Socket Weld pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for socket weld pipe flanges, the standard height is 1/16" for socket weld pipe flanges under 400#. For socket weld pipe flanges of 400# and up, the standard socket weld pipe flange raised face height is 1/4".

The Socket Weld pipe flanges include materials carbon socket weld pipe flanges, stainless steel socket weld pipe flanges and alloy socket weld pipe flanges available in various class such as 150 LBS, 300 LBS, 600 LBS, 900 LBS.
