ASTM B366 Inconel 625 Nickel Alloy Butt Weld Fittings Manufacturer in India

ASTM B366 Inconel 625 Butt Weld Fittings Manufacturer in India

Ganpat Metal manufactures and supplies certified ASTM B366 Inconel 625 Nickel Alloy Butt Weld Fittings conforming to ASTM B366 WPNICMC / ASME SB366 and ASME B16.9 / B16.28 standards. Inconel 625 is a nickel-chromium-molybdenum alloy with niobium addition that stiffens the alloy matrix without requiring precipitation-hardening heat treatment. It provides superior pitting and crevice corrosion resistance in marine and sour gas environments.

Our ASTM B366 Inconel 625 fittings portfolio includes 90° and 45° long and short radius elbows, straight tees, reducing tees, concentric and eccentric reducers, pipe caps, and stub ends. Available in seamless construction for ultra-high pressures and 100% X-ray inspected welded construction for large diameters, all fittings undergo rigorous solution annealing or normalizing heat treatment to assure superior metallurgical grain structure, ductility, and corrosion resistance.

We maintain deep inventories in sizes from 1/2" NB to 48" NB across schedules 10S, 40, STD, 80, XS, 160, and XXS. All fittings are beveled to ASME B16.25 for quick on-site fit-up and are supplied with EN 10204 Type 3.1 Mill Test Certificates from our Mumbai warehouse.

GM ASTM B366 Inconel 625 Fittings

GM handles enquiries for ASTM B366 Inconel 625 Fittings where buyers need to match fitting types (elbows, tees, reducers, end caps), nominal pipe sizes (NPS / DN), wall thickness schedules, and material grade to piping isometric drawings or project purchase specifications. The supplied inventory covers seamless and 100% X-ray welded fittings from 1/2" NB up to 48" NB across all schedules from Sch 10S to Sch XXS.

Grade selection should be based on the design pressure, service temperature, fluid media corrosivity, and mechanical strength requirements of the piping system. Buyers should also confirm the applicable manufacturing standard (ASME B16.9 / MSS-SP-43), weld bevel preparation (ASME B16.25), supplementary inspection requirements (radiography, PMI, hydrotest), and test documentation before finalizing an order.
