Detailed description

Socket weld flange (SW flange), a popular type of pipe flange, was initially developed for use on small-sized high- pressure piping. The fabrication of this type of flange is similar to that of a socket weld flange (WN flange). However, the internal pocket of a socket weld flange (SW flange) allows for a smooth bore and better fluid flow. When provided with an internal weld, the static strength of this flange is equal to slip-on flange, but the fatigue strength is 50% greater than double welding slip on flanges. Smooth bore conditions in such a flange can easily be attained without having to bevel the flange face and, after welding, to reface the socket weld flange as would be required with slip on flanges. For this reason, the internally welded flange is popular in chemical process piping.

Key Features:

The recess on the inside diameter of the socket weld flange (SW flange) allows for a good fit of the pipe allowing for a smooth flow of liquid.

Socket welding flanges work well for smaller sizes and higher pressure temperature conditions. They are similar to slip-on flanges, but must specify the schedule of the pipe where they will be used for with socket welds.

Application for socket weld flange (SW flange):

Natural gas,chemical,petroleum,ship building,marine,paper making, metallurgy, electric, power, boiler , etc.
