What is socket weld flanges?

Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These SWRF flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 24". We provide Socket Weld pipe flanges in all material grades, specifications and sizes.
Socket Weld 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 flanges under 400#. For socket weld pipe flanges of 400# and up, the standard socket weld pipe flange raised face height is 1/4".

Socket weld flange DIN EN 1092-1 is connected to a pipe with the help of a single fillet weld, that is executed on the outer side of the flange. Although the socket weld flange is different from the slip-on flange type, which requires two welds. according to ASME b31.1, the execution of socket weld flange connection using a socket weld flange is by first inserting the pipe in the socket of the flange until it reaches the bottom of the flange. This is then followed by lifting it by 1.6 mm and finally welded.
