Ganpat Metal manufactures and supplies industry-leading Carbon Steel Butt Weld Fittings conforming to ASTM A234 / ASME SA234 Grade WPB and Grade WPC. As the global benchmark piping material for moderate and elevated temperature systems, our carbon steel fittings provide outstanding toughness, structural integrity, and weldability in municipal gas pipelines, refinery process units, petrochemical plants, steam boilers, and chilled water networks.
Our carbon steel butt weld fittings program covers long radius (LR) and short radius (SR) 90° and 45° elbows, straight tees, reducing tees, concentric reducers, eccentric reducers, and pipe caps. Produced from prime seamless carbon steel pipe (ASTM A106 Gr. B/C) through hot mandrel expansion or cold forming followed by normalizing heat treatment, these fittings ensure uniform wall thickness and fine-grained microstructures.
We stock sizes from 1/2" NB to 48" NB across all schedules (Sch 20, 40, STD, 80, XS, 120, 160, XXS). All fittings are coated with black anti-rust primer or transparent oil and supplied with EN 10204 Type 3.1 certification and optional IBR (Indian Boiler Regulations) Form III-C.
GM handles enquiries for Carbon 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.
