We Petromat Oil & Gas Equipment Pvt. Ltd is one among the Leading Manufactures & Suppliers of Socket Weld Flanges within the grade stainless steel 304, 304L, 304H, 316, 316L, 316H. Socket Welding Flange is a popular sort of Pipe Flange, was initially developed to be used on small-sized high- pressure piping. The fabrication of this sort of Socket Weld Flange is comparable to that of a slip-on flange. However, the interior pocket of a socket weld flange allows for a smooth bore and better fluid flow. When given an inside weld, the static strength of this flange is up to slip-on flange, but the fatigue strength is 50% greater than double welding slip-on flanges. Smooth bore conditions in such a Socket Weld flange can easily to be attained without having to bevel the flange face and, after welding, to reface the socket weld Flange as would be required. For this reason, the internally Socket Welded Flange is popular in the chemical change piping.

Socket weld Flanges are used on smaller sizes of high-pressure pipes. These socket-weld pipe Flanges are attached by inserting the pipe into the socket end and applying fillet weld round the top. This enables for a smooth bore and better flow of the fluid or gas inside the pipe. Socket-weld flanges were initially developed to be used on small-size high piping. Socket-Weld Flanges features a female socket during which pipe is fitted. Fillet welding is completed from outside on the pipes.

Socket Weld Pipe Flanges are typically given a raised face, flat face, or RTJ facing. When a raised face is important for socket weld pipe flanges, the quality height is 1/16” for socket weld pipe flanges under 400#. For socket weld pipe flanges of 400# and up, the quality socket weld pipe flange raised face height is 1/4.” The aim for the bottoming clearance during a Socket Weld is typically to reduce the residual stress at the basis of the weld that would occur during solidification of the weld metal.

Advantages of Socket Weld Flanges

  • It is recommended for applications where internal welding operations are particularly difficult. This sock welded construction eliminates internal pockets while avoiding warpage of welding heat and damage to the flange face caused by weld spatter. it’s an equivalent internal pressure because the sliding on the flange, and features a better fatigue life.
  • Socket Weld Flange could replace threaded flange, to reduce the risky of leakage.
  • No got to beveling before welding.
  • Welding work outside of the pipe, won’t penetrate the pipe bore

Disadvantage of Socket Weld Flanges

  • Socket Welded Flange requires higher skills for welder, which the welding got to confirm that the expanding gap between the pipe and shoulder is 1/16 inch.
  • The expansion gap create the possibilities for the crack defects, especially for anti corrosive pipes as stainless steel pipes, therefore the cracks between the pipe and flange will cause the corrosive problems. SW flange won’t be compatible with environment, as this solid buildup at the joint can cause operational problems. So that’s why people use but welding more often because the welding completely through the pipe from outside to inside, which makes the connects more strong and anti corrosive.
