Other Details

The socket welding flange offered by us is a popular type of pipe flange that 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. Though, 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.

Material used:

    Alloy steel
    Carbon steel
    Stainless steel
    Cast iron
    Rubber
    PVC
    Thermoplastics
    Aluminum
    Brass
    Bronze

Key Features:

    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.
