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. Inconel 601 Pipe Fittings are manufactured and finished according to international standards ASTM B366 UNS N06601, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43 & MSS SP-75. Our range of Inconel 601 buttweld fittings includes Elbows, Tees, Cross, Cap, Reducers, Collars, Bends in all sizes and forms.

Inconel Elbow Fittings—Inconel 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 Inconel 601 elbows are mandrel formed to ensure consistency.

Inconel Return Bend Fittings— Bends are similar to elbows with different bending radiuses. Inconel 601 Bends are supplied as long radius return bends and short radius return bends.

Inconel Pipe Cross Fiittings—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.

Inconel 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.

Inconel 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.

Inconel 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.

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

Inconel 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 Inconel 601 alloy

Inconel 601 Cold Forming

The rate of cooling following hot-working is not critical with respect to thermal cracking. To avoid sensitization, however, the alloy should be cooled rapidly through the 1000-1400°F (540-760°C) temperature range. Inconel alloy 601 is cold-formed by conventional procedures. The alloy's work-hardening rate, is somewhat higher than the rate for Inconel alloy 600 and INCOLOY alloy 800.

Inconel 601 Hot Forming

The temperature range for hot-forming Inconel alloy 601 is 1600-2250°F (870-1230°C). Hot-working operations involving large deformations should be performed at 1900-2250°F (1040-1230°C). The alloy has low ductility at temperatures from 1200 to 1600°F (650-870°C) and should not be worked in that range. Light working at temperatures below 1200°F (650°C) can be done to develop high tensile properties.

Inconel 601 Machining

All standard machining operations are readily performed on Inconel alloy 601. For the best machinability, the alloy should be in the solution-treated condition.

Inconel 601 Welding

Inconel alloy 601 exhibits good weldability and is readily joined by conventional welding products and processes. Welding products are available which provide high joint efficiencies and heat resistance. The choice of welding product is dependent upon the service conditions to which the fabricated alloy 601 component will be exposed. Tensile properties of joints in Inconel alloy 601 are welded by the shielded-metal-arc, gas-tungsten-arc, and gas-metal-arc processes.

Inconel 601 Heat Treatment

Like other high-nickel alloys, Inconel alloy 601 must be clean before it is heated. All foreign substances such as grease, oil, paint, and shop soil must be removed from the material before a heating operation is performed. The alloy must be heated in a low-sulfur atmosphere. Fuels for open heating must be low in sulfur. To prevent excessive oxidation of the material, the furnace atmosphere should also be slightly reducing. Inconel alloy 601 is not strengthened by heat treatment. Broad ranges of strength and hardness, however, can be achieved with the alloy by the combination of cold work and annealing treatments. The amount of cold work and the section size of the material must be considered in establishing an annealing procedure.
