Socket Weld Flanges

OVERVIEW

Socket Weld Flanges

TUBA offer Socket Weld Flanges according to ASME, EN, ISO and DIN standards. ANSI B16.5 Socket Weld Flanges are very easy to recognize at any tampered hub, which goes gradually over to the wall thickness from a pipe or fitting. Socket-Weld Flanges has a female socket in which pipe is fitted. Fillet welding is done from outside on the pipe.

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. Our SWRF Flange Rating will help you to buy the correct Reducing Socket Weld Flange. We have extensive experience in supplying Socket Weld Flange are stocked or available in the following range of sizes and materials for the petrochemical, oil, gas, and allied industries.

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#. 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.
