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. 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. 309 Pipe Fittings are manufactured and finished according to international standards ASTM A403 WP309, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43 & MSS SP-75. Our range of 309 buttweld fittings includes Elbows, Tees, Cross, Cap, Reducers, Collars, Bends in all sizes and forms.

Stainlesss Steel Elbow Fittings—Stainlesss 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 A403 elbows are mandrel formed to ensure consistency. 309 Stainlesss Steel Elbow Fittings and Stainlesss Steel Elbow Fittings is in ready stock with Siddhagiri Metals and Tubes.

Stainlesss Steel Return Bend Fittings— Bends are similar to elbows with different bending radiuses. ASTM A403 Bends are supplied as long radius return bends and short radius return bends. 309 Stainlesss Steel Return Bend and Stainlesss Steel Return Bend is in ready stock with Siddhagiri Metals and Tubes.

Stainlesss 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. 309 Stainlesss Steel Pipe Cross and Stainlesss Steel Pipe Cross is in ready stock with Siddhagiri Metals and Tubes.

Stainlesss 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. 309 Stainlesss Steel End Cap and Stainlesss Steel End Cap is in ready stock with Siddhagiri Metals and Tubes.

Stainlesss 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.

Properties of AISI 309 Stainlesss Steel

309 SS Cold Forming

The alloy is quite ductile and forms in a manner very similar to 316. Cold forming of pieces with long-term exposure to high temperatures is not recommended since the alloy is subject to carbide precipitation and sigma phase precipitants.

309 SS Hot Forming

Heat uniformly at 1742 – 2192°F (950 – 1200°C). After hot forming a final anneal at 1832 – 2101°F (1000 – 1150°C) followed by rapid quenching is recommended.

309 SS Welding

Alloy 309 can be readily welded by most standard processes including TIG, PLASMA, MIG, SMAW, SAW and FCAW.
