Forged fittings
Forged steel fittings are pipe fittings that are made from forged carbon steel material. Forging steel is a process that creates very strong fittings. Carbon steel is heated to molten temperatures and placed in the dies. The heated steel is then machined into the forged steel fittings.
Stainless steel forged fittings are essential components of some industrial or commercial systems, making the joining of two or more pipes, possible. Piping systems less than 2 or 4 inches in diameter generally use forged fittings and differ from buttweld fittings used for piping systems with larger diameters.
Types of Forged Fittings
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.
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.
Plug
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.
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.
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.
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.
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.
Caps
Caps are forged steel fittings used to terminate the flow, inserting over the end of the pipe.
