1. Introduction

Socket welding 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 re-face 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.

The counter bore is slightly larger than the Outer Diameter of the matching pipe, allowing the pipe to be inserted. A restriction is built into the bottom of the bore, which acts as a shoulder for the pipe to rest on, and has the same I.D. of matching pipe. The flow is not restricted in any direction.
