Socket Weld Flange


When undergoing with large pressure pipes having a tiny low size, we’d like Socket Weld Flange. Though they’re the same as wear flange, Socket Weld Flange contains an indoor recess inside its diameter that ensures sleek flow. Moreover, the foremost advantage of Socket Weld Flange is that with correct attachment and grinding, it makes sleek bore. However, Socket welds are sold at high value as they need knotty machining. Then, Socket Weld Flange was created with associate degree intention for usage in hard-hitting areas at little pipes.
FittingCart has the simplest warehouse facilities that have an enormous stock of Socket Weld Flange able to ship and are accessible altogether dimensional inches. On the opposite hand, we tend to conjointly furnish flange with 1/16’’ raised face once such as by customers. Alternative flat face choices also are accessible and furnishing of normal Bore is additionally done. As matter of truth, we tend to conjointly supply Socket Weld Flange in numerous materials like alloy, chrome steel, steel and a lot of.
Another output that Hydro manufactures is Socket Weld Insert flange. This type of flange permits you to rotate outer flange simply as they are available in an exceedingly two-piece. Hence, providing you with straightforward bolt whole alignments. We tend to conjointly create one piece socket weld insert flange if asked for. Accurately, the two-piece Socket Weld Flange encompasses a dimension of DN15 – DN2000 (1/2″ – 80″). Socket Weld Flange have a fatigue strength of doubly the double-welded don the flange. Of course, bear in mind to form an area between flange and pipe before attachment. This may facilitate scale back stress at the weld root.

Industrial Processes

Die formation, Machining

The standard level for pressure-temperature ratings, tolerances, dimensions, marking and material necessities for steel and solid carbon fittings is B16.11. By identical token, different types of materials embrace forgings, seamless tubes, bars and seamless pipe that square measure relevant to the fittings chemical compositions, mechanical property, and melting practices meet the necessities of ASTM A105, A182, or A350. In keeping with ASME B31.1 levels, for the preparation of Socket Weld Flange, the pipes ought to be inserted into the socket to the utmost depth followed by retreating 1/16’’ (1.6mm) off from the contact of shoulder socket and pipe finish within the assembly of the joint before fastening

In my opinion, the intention of bottoming clearance during a socket weld flange is simply to decrease the residual pressure at the foundation of the weld that will begin whereas the continuing method of hardening of the fastening metal.


Pros and Cons of Socket Weld Flange


  • No beveling of the pipe is critical before fastening.
  • Any temporary tack fastening isn’t necessary for alignment because the flange ensures excellent alignment.
  • The bore of the pipe doesn’t let weld metal penetrate into itself.
  • Probabilities of the leak are less if replaced to string fittings.
  • Prevents radiography victimization its fillet.
  • Budget friendly construction expenses as they match precisely thus no special tools and installments.


  • The need of growth gap of 1/16 in. between the socket shoulder and also the pipe.
  • The presence of crevices and gap will result in corrosion.
  • Not applicable for immoderate High hydrostatic Pressure as they don’t permit complete penetrate.
