ASTM A234 • Alloy Steel Fittings • 4130 Steel Pipe Fittings • 4130 Chromoly Pipe Fittings Supplier

Siddhagiri Metals and Tubes is a supplier of AISI 4130 Pipe Fittings as per ASTM A234. We are an ISO 9001:2015 certifed company with Alloy Steel Pipes exports in more than 70 countries gloablly. AISI 4130 is a versatile low carbon Chromium-Molybdenum Alloy with good strength and toughness.

A fitting is used in pipe systems to connect straight pipe or tubing sections, adapt to different sizes or shapes and for other purposes, such as regulating fluid flow. SAE 4130 Pipe Fittings are used in a piping system to change direction or function, which is mechanically joined to the system. The simplest way to achieve this is to bend the pipe in the direction required, but this process will stretch and thin the outer wall of the pipe whilst thickening and wrinkling, the inner wall of the pipe. This results in flow resistance and accelerated wall erosion. 4130 Steel Pipe Fittings are manufactured and finished according to international standards ASTM A234, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43 & MSS SP-75. Our range of 4130 Steel buttweld fittings includes Elbows, Tees, Cross, Cap, Reducers, Collars, Bends in all sizes and forms.

Alloy Steel Elbow Fittings—Alloy Steel Pipe Elbows are installed between two lengths of pipe or tube allowing a change of direction by 180°, 90° or 45°. The ends are machined for Butt Welding when the two ends differ in size, it is called a Reducer or, Reducing Elbow. Pipe Fitting Elbows are available as 180° elbows, 90° elbows or 45° elbows in 1D, 1.5D, 2D, 3D, 5D, 6D, 8D, 10D radius as short and long radius elbows. All ASTM A234 elbows are mandrel formed to ensure consistency.

Alloy Steel Return Bend Fittings— Bends are similar to elbows with different bending radiuses. ASTM A234 Bends are supplied as long radius return bends and short radius return bends.

Alloy Steel Pipe Cross Fittings—Pipe Fitting Cross are used in several industries for providing the leak free and torque free sealing in any piping or tubing connection known for their close tolerances.

Alloy Steel Cap Pipe Fittings—The function of a Pipe Cap is to block off the end of a line in an industrial piping system. Pipe Cap is fitted by placing the end cap over the open line and welding around the joint.

Alloy Steel Tee Pipe Fittings—Pipe Fitting Tee is widely used in industrial piping systems to merge or divide fluids and do not require special tubing preparation before installation. Tees are available in different threading specifications and are engineered to close tolerances and precise dimensions.

Alloy Steel Stub Ends Pipe Fittings—Stub Ends are installed in pairs and mated together with two Lap-Joint Flanges. The surface of the stub end has a phonographic serrated gasket surface which prevents leakage at the joint. Using stub ends allows sections of the line to be opened for cleaning, inspection or quick replacement, etc, without the need to re-weld.

Alloy Steel Pipe Reducer Fittings— Reducers are supplied as Eccentric Reducer, Concentric Reducer and Conical Reducer or Bell Shaped Reducer.

Alloy Steel Pipe Coupling— Couplings are used to merge two equal ends in a piping system. Couplings are classified as half-coupling and full-coupling.
