Forged Alloy Steel Socket Weld & Threaded Pipe Fittings Manufacturing Standards

  • ASTM A182 – ASME SA182 – Standard Specification for Wrought Austenitic Stainless Steel Piping Fittings
  • ASME B16.9 – Factory-Made Wrought Buttwelding Fittings
  • ASME B16.11 – Socket Welding and Threaded Forged Fittings
  • MSS SP-43 – Wrought and Fabricated Butt-Welding Fittings for Low Pressure, Corrosion Resistant Applications
  • MSS SP-95 – Swage(d) Nipples and Bull Plugs
  • BS3799 – Specification for Steel pipe fittings, screwed and Socket-welding for the petroleum industry

Forged Pipe Fittings (Socket Weld and Threaded) are made in accordance to ASME B16.11, MSS-SP-79\ 83\ 95\97 and BS3799 standards, and are used to connect nominal bore schedule pipes and pipelines. A socket weld pipe fitting, abbreviated as SWF, is one where the pipe is inserted into a recessed area of the fitting. To make a socket weld fitting, the pipe is inserted into the pipe before it is welded. In order to prevent damage to the pipe and fitting, the pipe is then backed out a minimum of 1/16” to allow for thermal expansion of the pipe during the welding procedure. If this clearance is not made, the weld can crack due to the pipe expanding against the fitting. Socket weld flange with pipe SW Fittings are used for piping that has a nominal pipe size (NPS) of 3 inches and below. The applications range from chemical, petrochemical, power generation and OEM manufacturing industry as well other applications where vibration, high pressure or extremely corrosive conditions exist.

Alloy steel socket weld fittings are generally used for small size pipes and piping systems (generally below 4 inches in diameter for Class 3000, and below 2 inches for fittings in class 6000 and 9000). Alloy steel socket weld pipe fittings are manufactured by forging, followed by heat treatment and machining solid steel as per ASME B16.11 and other dimensional standards. For bigger size piping systems buttweld pipe fittings produced as per ASME B16.9 are used.

Manufacturing Process for Alloy Steel Socket Weld Forged Fittings

  • Forged fittings are the fittings made by forged steel. The process of manufacturing forged steel fittings include: cutting and heating billets, put pressure on heated billets under dies into desired shape, trimming and shot blasting. Then machine forged blank fittings for net shape and dimensions. According to the applications of forged steel fittings, they are available in threaded and socket weld end connections.

The main raw material for producing forged pipe fittings is round bar stock or billets.

  • Most of the forged steel fittings are not large, so closed die forging is normally adapted to produce forged steel fittings. Compared to the open die forging, the close die forging can achieve more complex geometries, very much close to the dimensions of the finished component.
  • Close die forging can produce forged fittings in all materials such as carbon steel, duplex, stainless steel or nickel alloys.

Equipment’s Used in Alloy Steel Socket Weld Pipe Fittings

  1. The equipment used to produce pipe fittings varies with respect to the forging processes which can be carried out:
    • The method of applying the force.
    • The size.
  2. The different types of forging equipment include:
    • Hammers
    • Presses
    • Upsetters
    • Forging Rolls
    • Ring Rollers
    • Swaging Machines

Elbows (90 Degree Elbows and 45 Degree Elbows) – A pipe elbow is a forged steel fitting installed between two lengths of pipe or tube allowing a change of direction, usually in the 90° or 45° direction. Similar to a reducing tee, reducing elbows also exist to simultaneously change flow direction and reduce flow diameter. Street Elbows have one female end to accept pipe and another male end thread that is the same size as the pipe and can avoid the use of a pipe nipple during installation.

  1. Tees (Equal Tee and Reducing Tees)- Tees are a type of forged steel fitting used to combine or divide process flow, and Reducing Tees additionally allow for pipe size change. The run outlets of the tee are the two in-line outlets, and the branch is the third outlet. The branch outlet is the reducing outlet in a reducing tee.
  2. Couplings (Straight and Reducing Couplings, Full and Half Couplings) – Couplings are a forged steel fitting used to connect two lengths of pipe, and Half-coupling is screwed onto the pipe, while the other end is made to be tightly inserted, or welded, onto the other end to pipe or vessel. Standard Couplings have female threads or open sockets at both ends, whereas reducing couplings connect smaller pipes to larger ones.
  3. Unions– Unions are a forged steel fitting similar to a coupling but allow a convenient disconnection and connection; it has 3 parts: a nut, a female end, and a male end. They allow two lengths of pipe to be assembled and detached without causing any deformation to the pipes.
  4. Bushings (Hex Head Bushings and Flush Bushings) – Reducing inserts and Bushings are forged steel fittings that allow for a change in pipe size. Pictured here is the hex head bushing, which is most commonly used.
  5. Caps (Pipe Caps and End Caps) – Caps are forged steel fittings used to terminate the flow, inserting over the end of the pipe.
  6. Plug (Square Head Plugs, Hex Head Plugs and Round Head Plugs) – Similar to a cap, plugs are forged steel fittings that are inserted into the end of the pipe, and they come with different head types, including: hex, square, and round.
  7. Cross – Crosses are a 4-way forged steel fitting, with 1 inlet and 3 outlets or vice versa. These are sometimes referred to as 4-way tees.
  8. Outlets (Weldolets, Sockolets, Threadolets, Elbolets, Latrolets and Nipolets)
  9. Nipples (Hexagonal Nipples and Swaged Nipples)

Chemical Composition of Alloy Steel Socket Weld Pipe Fittings

Low-alloy forged fittings match chrome-moly pipes ASTM A335 in grades P5 (for F5 fitting), P9 (for F9 fitting), P11 (for F11 fitting), P22 (for F22 fitting), P91 (for F91 fittings). The chemical composition of these common alloy grades for socket weld and threaded fittings is shown below:

Disadvantages of Alloy Steel Socket Weld Pipe Fittings

There are also some shortfalls in using socket weld fittings. If the welder does not leave a gap between the pipe and the shoulder of the socket, there is a risk that the weld will fail either during the welding process or under high temperatures. This gap can cause solids to accumulate which can cause corrosion issues. If the piping is used for multiple process fluids, this accumulation may contaminate the additional process streams.

Difference Between Socket Weld Pipe Fittings and Threaded Pipe Fittings

  1. Socket weld fittings are used for applications where strong and long-lasting connections are required.  Socket weld fittings are very reliable but are time-consuming to install in a piping system (due to the heavy workload caused by welding operations on small parts). Threaded fittings are used for less-critical piping systems, such as water distribution, fire protection, and cooling, or for low-pressure installations not subject to vibration, elongation and bending forces. Threaded pipe fittings are not suited for fluids with constantly changing temperatures, as sudden changes may crack the connection.
  2. Socket weld fittings are connected to pipes by fillet welds, whereas threaded fittings are screwed onto the pipe or vice-versa.
