DN 40 Socket flanges

　　Socket flanges are typically used on smaller sizes of high pressure pipes. These pipe 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".

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