What Is Socket Weld Fittings?

A Socket Weld Fittings is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting, or flange. In contrast to buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.
To join pipe to Valves and fittings or to other sections of pipe, fillet-type seal welds be used. Socket Welded Joints construction is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations.
Fatigue resistance is lower than that in butt-welded construction due to the use of fillet welds and abrupt fitting geometry, but it is still better than that of most mechanical joining methods.
The purpose for the bottoming clearance in a Socket Weld is usually to reduce the residual stress at the root of the weld that could occur during solidification of the weld metal, and to allow for differential expansion of the mating elements.

Socket Weld Fittings are family members of high pressure pipe fittings, which available in rating of Class 3000lb, 6000lb and 9000lb. They are used in areas where pipe-work is permanent and are designed to provide good flow characteristics. Usually in conjunction with with ASME Pipe and are available in the same size range. We produced forged steel fittings in accordance with ASME B16.11. The B16.11 standard covers pressure-temperature ratings, dimensions, tolerances, marking, and material requirements for forged carbon and alloy stainless steel. The chemical and mechanical property requirements are conform to ASTM A105, A182 or A350.

Few More Details About Socket Weld Fittings

Socket Weld Fittings are a family of high-pressure fittings that are used in various industrial processes.

  • They are used for lines conveying flammable, toxic or expensive material where no leakage can be permitted, and for steam 300 to 600 PSI.
  • They are used only in conjunction with ASME Pipe and are available in the same size range.
  • They are used in areas where pipe-work is permanent and are designed to provide good flow characteristics.
  • They are produced to several ASTM standards and are manufactured in accordance with ASME B16.11. The B16.11 standard covers pressure-temperature ratings, dimensions, tolerances, marking, and material requirements for forged carbon and alloy steel. Acceptable material forms are forgings, bars, seamless pipe, and seamless tubes which conform to the fittings chemical requirements, melting practices, and mechanical property requirements of ASTM A105, A182, or A350.
  • They are available in three pressure ratings: Class 3000, 6000, and 9000.
  • Standard for Socket Weld Fittings

  • Forged stainless steel material conforms to ASTM A182
  • Forged steel fitting dimensions conform to ASME B16.11
  • Socket weld fittings conform to ASME B16.11
  • Forged socket weld union conform to MSS SP-83
  • Stainless steel outlets conform to MSS SP-97

    Socket Weld Fittings Products

  • Socket Weld Elbow:- can make 45 degree and 90 degree changes the direction in the flow of pipe. You do not need to do bevel weld preparation for pipes. They have same function with threaded fittings.
  • Socket Weld Coupling:- is meant to joint a pipe into a recessed area of valves, fittings and flanges. Full coupling is usually to joint pipe to pipe or nipple, while half coupling is a combination of provision. We can join one end by welding and other side of with socket weld. They are available in various of sizes, thickness, pressure ratings according to customer’s requirements.
  • Socket Weld Cross:- can makes 90 degree branch from the main run of pipe.It is used to change the direction of the line in the piping system.
  • Socket Weld Tee:- are mainly forming by the round steel or ingot molding forging, and then machined to be a high-pressure pipeline connection accessories. If the branch diameter is same as run pipe, we call it as SW Equal Tee. Otherwise, it is Socket Weld Reducing Tee.
  • Socket Weld Cap:- is meant to insert a pipe into cap and weld for sealing the pipe end. Same function as threaded plug and blind flanges.
  • Socket Weld Reducing Inserts:- comply with MSS SP-79 standard. They can make any combination of pipe line reductions quickly and economically.
  • Difference Between Socket Weld Fittings VS Cast Fittings

    Stainless steel forged socket weld fittings are engineered to be stronger than cast fittings.
    Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape.
    Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state.This process alters the grain of the steel causing it to be mechanically stronger and more reliable with a high impact tolerance. Forged steel also has a high wear resistance because of the tighter grain structure of the steel.

    Socket Weld Fittings Advantages Are:

  • The pipe need not be beveled for weld preparation.
  • Temporary tack welding is no needed for alignment because in principle the fitting ensures proper alignment.
  • The weld metal can not penetrate into the bore of the pipe.
  • They can be used in place of threaded fittings, so the risk of leakage is much smaller.
  • Radiography is not practical on the fillet weld; therefore correct fitting and welding are crucial. The fillet weld may be inspected by surface examination, magnetic particle (MP), or liquid penetrant (PT) examination methods.
  • Manufacturing costs are lower than with butt-welded joints due to the lack of exacting fit-up requirements and elimination of special machining for butt weld end preparation.
  • Socket Weld Fittings Disdvantages Are:

  • The welder should ensure for a expansion gap of 1/16 inch (1.6 mm) between de pipe and the shoulder of the socket. ASME B31.1 para. 127.3 Preparation for Welding (E) Socket Weld Assembly says:-
    In assembly of the joint before welding, the pipe or tube shall be inserted into the socket to the maximum depth and then withdrawn approximately 1/16" (1.6 mm) away from contact between the end of the pipe and the shoulder of the socket.
  • The expansion gap and internal crevices left in socket welded systems promotes corrosion and make them less suitable for corrosive or radioactive applications where solids buildup at the joints may cause operating or maintenance problems. Generally require butt welds in all pipe sizes with complete weld penetration to the inside of the piping.
  • Socket welding are unacceptable for UltraHigh Hydrostatic Pressure (UHP) in Food Industry application since they do not permit full penetration and leave overlaps and crevices that are very difficult to clean, creating virtual leaks.
