Introduction of socket welding flange

What is a socket welding flange?

Socket welding flange 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.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 of socket welding flange:

The recess on the inside diameter of the socket weld 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.
