Introduce the usage and advantages of the socket flange

　　Socket flange simplified as SW flange, it has a recessed area (like a shoulder) in the flange bore, this shoulder serves as a guide to set the depth of the pipe that inserted to the flange. Socket flange initially designed for high pressure small diameters piping system.

　　How to Use

　　Insert the pipe end into socket weld flange, until the pipe bottom touch the shoulder area, pull back 1.6mm (1/16'') distance of the inserted pipe then do fillet welding. The point is to create a expansion gap (1 fillet weld) between the flange and the pipes or fittings.

　　Advantages

　　•Socket flange could replace threaded flange, to minimize the risky of leakage.

　　•No need to beveling before welding.

　　•Welding work outside of the pipe, will not penetrate the pipe bore

　　•It is recommended for applications where internal welding operations are particularly difficult. This sock welded construction eliminates internal pockets while avoiding warpage of welding heat and damage to the flange face caused by weld spatter. It has the same internal pressure as the sliding on the flange, and has a better fatigue life.
