We are the ISO approved manufacturer of steel pipe fittings. Socked Weld Elbow is available in Stainless Steel, Corbon Steel and Alloy Steel.

These Stainless Steel Pipe Fittings are best known for their heat resistance, creep strength and tensile strength. Machined and fabricated to meet your diverse piping requirements, these pipes fittings exhibit excellent corrosion resistance in a wide range of atmospheric environments.

ASME B16.11 is the standard contains ratings, dimensions, tolerances, marking and material requirements for forged fittings, both socket-welding and threaded. Threaded fittings are available in pressure ratings Class 2000, 3000, and 6000;

Socket welding fittings are available in pressure ratings Class 3000, 6000, and 9000.

Generally, both fittings size range is 1/8″- 4″or DN6-DN100.

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. Once correctly inserted, fillet type sealing welds are applied to join the pipe to the fitting.

Different from 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.

These fittings are commonly called SW pipe fittings that include elbows, tees, cross, caps, coupling and union.

Socket welds can be used to change the direction of travel for pipe networks as well as join pipes at different angles and of different diameters.

The function of elbow is to change direction or flow in a piping system. There are the 45°, 90° and 180° elbows

Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.

According to the production method, it can be divided into pushing, pressing, forging, casting, etc.

According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).
