Ganpat Metal manufactures and supplies certified Stainless Steel Butt Weld Fittings in Grade ASTM A403 WP304, WP304L, WP316, WP316L, WP321, and WP347 conforming to ASME / ANSI B16.9, ASME B16.28, and MSS-SP-43. Our precision fittings are engineered for leak-free, high-integrity piping systems in oil & gas, chemical, petrochemical, food & dairy, pharmaceutical, and offshore marine industries.
Our stainless steel fittings inventory includes 90° and 45° elbows (long and short radius), equal and reducing tees, concentric and eccentric reducers, end caps, and stub ends. Available in seamless construction for ultra-high-pressure applications and 100% X-ray radiography tested welded execution for large-diameter lines, all fittings undergo rigorous solution annealing to restore corrosion resistance and ensure ductile mechanical properties.
We supply sizes from 1/2" NB to 48" NB across schedules 5S, 10S, 40S, 80S, 160, and XXS. All fittings are beveled to ASME B16.25 and supplied with EN 10204 Type 3.1 Mill Test Certificates from our central Mumbai distribution warehouse.
GM handles enquiries for Stainless Steel Butt Weld 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.
