When operating with large pressure pipes having a little size, we want Socket Weld Flange. Though they’re like wear flange, Socket Weld Flange comprises an interior recess inside its diameter that ensures swish flow. Moreover, the main advantage of Socket Weld Flange is that with correct fastening and grinding, it makes swish bore. However, Socket welds square measure oversubscribed at high price as they need complex machining. Then, Socket Weld Flange was created with Associate in nursing intention for usage in hard-hitting areas at little pipes.Duplex Supply has the simplest warehouse facilities that have a large stock of Socket Weld Flange able to ship and square measure accessible all told dimensional inches. On the opposite hand, we have a tendency to additionally furnish flanges with 1/16’’ raised face once such by customers. Alternative flat face choices are accessible and furnishing of normal Bore is additionally done. As matter of truth, we have a tendency to additionally supply Socket Weld Flanges in varied materials like alloy, stainless-steel, steel and additional.Another output that Duplex Supply manufactures is Socket Weld Insert projection. This type of flanges permits you to rotate outer flange simply as they are available in a very two-piece. Hence, providing you with straightforward bolt hole alignments. We have a tendency to additionally build one piece socket weld insert flanges if asked for. Accurately, the two-piece Socket Weld Flange includes a dimension of DN15 – DN2000 (1/2″ – 80″). Socket Weld Flange have a fatigue strength of double the double-welded get into the projection. Of course, bear in mind to form an area between projection and pipe before fastening. This can facilitate scale back stress at the weld root.

Types of Socket Weld Flange
  • Class Designation- 3000 Lbs., 6000 Lbs., 9000 Lbs.
  • Elbows forty five degrees, Elbow ninety degree, Tees, Crosses, Couplings, Half-Couplings, finish or Pipe Caps all starting from ½ – four to ½ – a pair of two ½ – a pair of.

  • Metal Flanges- ASTM B 366, etc.

To attach this Socket Weld Flange, first of all insert the pipe within the Socket finish and at the highest aspect unfold the fillet weld. Further, this offers a swish flow within the pipe. Duplex Supply is the manufacturer and provider of Socket Weld Flange that is accessible in varied sizes, material grades, and specifications. Above all, our company additionally produces get into Flanges with a hub that has such as vary ranging from 1/2’’ via 24’’. In fact, they’re furnished a flat face, raised face with 1/16’’ or RTJ facing, our Socket Weld Flanges square measure possible in carbon, steel, chrome steel and alloy Socket Weld Flange.

Applications of Socket Weld Flange
  • Applicable for lines conveyance inflammable, dear or ototoxic material for steam three hundred to 600 PSI with no leaks.
  • helpful in conjunction with ASME Pipe and are offered within the same size vary.
  • Usage in areas of permanent pipe-works and are designed to produce smart flow characteristics.
  • They are created to many ASTM standards and are factory-made in accordance with ASME B16.11.
  • They’re offered in 3 pressure ratings: 3000lbs, 6000lbs, and 9000lbs
  • Process plant for chemical element, element and carboxylic acid acids, and Pulp and paper process.
  • Elements in gas cleansing plants and saltwater cooling instrumentality
  • Refinery elements and Wires in static precipitators.

In my opinion, the intention of bottoming clearance in an exceedingly Socket Weld Flange is simply to decrease the residual pressure at the foundation of the weld that will begin whereas the continuing method of solidifying of the attachment metal.
