Socket welding 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
slip-on flange. However, the internal pocket of a socket weld
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. Product
