Siddhagiri Metals and Tubes is a manufacture and exporter of qualityCopper Nickel Pipe Fittings as per ASTM B466. We are an ISO 9001:2015 certified and CRISIL MSE 4 rated company with global exports of CuNi Pipe Fittings.
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. 70 30 CuNi Pipe Fittings are manufactured and finished according to international standards ASTM B466 UNS C71500, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43 & MSS SP-75. Our range of 70 30 CuNi Pipe fittings includes Elbows, Tees, Cross, Cap, Reducers, Collars, Bends in all sizes and forms.
Copper Nickel Elbow Fittings—Copper Nickel 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 B466 elbows are mandrel formed to ensure consistency.
Copper Nickel Return Bend Fittings— Bends are similar to elbows with different bending radiuses. ASTM B466 Bends are supplied as long radius return bends and short radius return bends.
Copper Nickel 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.
Copper Nickel 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.
Copper Nickel 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 dimension standards ASME /ANSI B16.9 and ASME / ANSI B16.28.
Copper Nickel 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.
Copper Nickel Pipe Reducer Fittings— Reducers are supplied as Eccentric Reducer, Concentric Reducer and Conical Reducer or Bell Shaped Reducer.
Copper Nickel Pipe Coupling— Couplings are used to merge two equal ends in a piping system. Couplings are classified as half-coupling and full-coupling.

Properties of 70 30 CuNi alloy
70 30 Copper-Nickel Cold Forming and Hot Forming
With good hot and cold working properties, copper nickel alloy responds well to most fabrication processes. Due to properties inherited from Copper, Copper-Nickel alloy is can be easily drawn and spin.
70 30 Copper-Nickel Machining
Copper-nickels can be cut using most conventional cutting processes. Plasma-arc cutting is fast, accurate and economical. Laser and abrasive water jet cutting are also possible The machinability rating of 70 30 copper-nickel alloy is 20%.
70 30 CuNi Welding
Copper Nickel Alloys can be easily joined by soldering, brazing and a variety of welding methods such as gas shielded arc welding, spot welding, coated metal arc welding, butt welding, seam welding, brazing, soldering and oxyacetylene welding processes.
70 30 CuNi Corrosion Resistance
Copper-nickel Alloys have good resistance to chloride pitting and crevice corrosion. They have excellent corrosion resistance against moisture, non-oxidising acids, alkalis and salt solutions, organic acids and to gases such as oxygen, chlorine, hydrogen chloride, hydrogen fluoride, sulphur dioxide and carbon dioxide. It is found that the corrosion rates of CuNi alloys are 0.02-0.002mm/year in sea-water.
