All of our manufactured products are subject to the rigirous audit process, which allow us to deliver quality products that meet customer requirements at low cost.

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. Hastelloy C276 Pipe Fittings are manufactured and finished according to international standards ASTM B366 UNS N10276, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43 & MSS SP-75. Our range of Hastelloy C276 buttweld fittings includes Elbows, Tees, Cross, Cap, Reducers, Collars, Bends in all sizes and forms.

Hastelloy Elbow Fittings—Hastelloy 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 B366 elbows are mandrel formed to ensure consistency.

Hastelloy Return Bend Fittings— Bends are similar to elbows with different bending radiuses. ASTM B366 Bends are supplied as long radius return bends and short radius return bends.

Hastelloy 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.

Hastelloy 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.

Hastelloy 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.

Hastelloy 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.

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

Hastelloy 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 Hastelloy C276 alloy

Hastelloy C276 Cold Forming

Annealed treatment is followed for every forming operations. For cold deformation at high-level, cold forming is done for the deformation process where cracking is a possibility because of mild forming. The cold forming process is used to restore the resistance to stress corrosion cracking. For most of the time, a solution anneal is recommended after the complete formed or annealed operation which helps to restore the material to its optimum condition and properties.

Hastelloy C276 Hot Forming

Hastelloy C276 can be hot-worked into various forms but they are more sensitive to the amounts and rates of hot-reduction with the austenitic stainless steels. During Hot working, all parameters should be taken into account. Special attention should be given to the temperature at which the alloy begins to melt. The high strengths of the Hastelloys at elevated temperature, their low thermal conductivity, and their hardening rate. Moreover, when the temperature is low in the hot working range of the metal, they are resistance to deformation is increased rapidly. So, while hot working practices that give heavy initial reduction followed by moderate final reductions, also with frequent re-heating gives the good result.

Hastelloy C276 Machining

Hastelloy C276 can be machined using conventional production methods at satisfactory rates. During the machining processes these alloys work harden rapidly, generate high heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths. Following are key points that should be considered during machining operations: Capacity, Tooling, Lubrication/Coolants, Drilling. The actual operating parameters are to serve only as a guide and are not to be taken as absolute values.

Hastelloy C276 Welding

Gas tungsten-arc welding, gas metal-arc welding, shielded metal-arc (coated electrode) welding, or resistance welding may be used. Minimum heat input consistent with adequate penetration reduces the chance of hot-cracking. Oxyacetylene welding should be avoided due to possibility of carburization. Hastelloy C-276 can be used in the as-welded condition in most chemical and petrochemical process equipment

Hastelloy C276 Heat Treatment

Wrought forms of Hastelloy C-276 are furnished in the solution heat-treated condition unless otherwise specified. Alloy C-276 is normally solution heat-treated at 2050 °F and rapid quenched. Parts which have been hot-formed should be solution heat-treated prior to final fabrication or installation, if possible
