Socket Weld Elbow Fittings
The Socket Weld Elbow Fitting is a pipe fitting installed between two lengths of pipe or tube allowing a change of direction, usually 90° or 45°. The ends can be be machined for screwed (usually female), or socketed. When the two ends differ in size, it is called a Reducing or Reducer elbow.
Most elbows are available in short radius or long radius of types. The short radius elbows have a center to end distance equal to the NPS in inches, while the long radius is 1.5 times the NPS in inches.
Socket Weld Tee Fittings
A Socket Weld Tee Fitting is used to either combine or split a fluid flow. The most common Socket Weld Tees have the same inlet and outlet sizes, but ‘Reducing’ Socket Weld Tees are available as well.
Socket Weld Cross Fittings
A Socket Weld Cross Fitting has one inlet and three outlets, or vice versa.
Socket Weld Couplings
A Socket Weld Pipe Coupling fitting connects two pipes to each other. If the material and size of the pipe are not the same, the fitting may be called a ‘Reducing Coupling’ or Reducer, or sometimes an Adapter.
Socket Weld Cap Fittings
A Socket Weld Cap is a type of pipe fitting, usually liquid or gas tight, which covers the end of a pipe to stop flow. A Cap has a similar function to a Plug.
Socket Weld Union Fittings
A Socket Weld Union Pipe Fitting is similar to a Coupling, except it is designed to allow quick and convenient disconnection of pipes for maintenance or fixture replacement. While a Coupling would require either solvent welding or being able to rotate all the pipes adjacent as with a Threaded Coupling, a Union provides a simple nut transition, allowing easy release at any time.
Pipe Nipples and Barrel Nipples
A Pipe Nipple or Barrel Nipple is defined as being a short stub of pipe which has two male ends. Nipples are commonly used for plumbing and hoses, and second as Valves for funnels and pipes.
Concentric Swages and Eccentric Swages
The most common use of Swaging is to attach fittings to pipes or cables (also called wire ropes); the parts loosely fit together, and a mechanical or hydraulic tool compresses and deforms the fitting, creating a permanent joint. Pipe flaring machines are another example. Flared pieces of pipe are sometimes known as “Swage Nipples,” “Pipe Swages,” or “Reducing Nipples.
Socket Weld Reducing Inserts
This is a Socket Weld version of a Bush. Reducer Insertscomply with MSS Standard SP-79. They enable standard Socket Weld Fittings to be used for making any combination of pipe line reductions, quickly and economically. Socket Weld Reducer Inserts serve the same purpose as Threaded Reducing Bushings with threaded fittings.
Buttweld Branch Outlet Fittings
“Outlet” is a generic term for all branch type connections. They can come with Threaded, Socket Weld, and Butt Weld end connections. The most common types are used in place of a Tee. A hole is cut in the side of the pipe, the Outlet is welded in place over the hole and then the additional length of pipe is attached to the Outlet.
Similar to reducing Tees, Outlets are usually described by two sizes. The Run or Header size refers to the pipe on which the Outlet is mounted. The Outlet or Branch size refers to the length of pipe branching off of the run.
This type of fitting is contoured to match the curve on the Header Pipe and beveled on the Branch side to mate up with a beveled piece of the branch pipe.
