What is a SW Flange
Socket-weld pipe 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.
Socket weld flange is designed as the pipe is inserted into it’s bore and single fillet weld on the outside of flange. It is common used for small diameter high-pressure piping system. To some extent, it is smilar to slip on flange.
Forged steel flange is a disc-shaped piece of equipment used to connect a pipe to fittings or valve or other component to form a pipework system. Usually flange has been attached to pipe or tube end to, and then a gasket is inserted in the middle to form a seal. Finally they are joined together with bolts and nuts.
