Ganpat Metal manufactures and supplies certified Alloy Steel Butt Weld Fittings conforming to ASTM A234 / ASME SA234 Grade WP5, WP9, WP11, WP22, and WP91. Engineered specifically for moderate and elevated temperature service, these chromium-molybdenum alloy steel fittings deliver exceptional creep rupture strength, graphitization resistance, and hydrogen attack immunity in power boilers, fired heaters, and high-pressure steam distribution systems.
Our alloy steel fitting portfolio includes 90° and 45° elbows, tees, concentric and eccentric reducers, and caps manufactured by hot mandrel pushing or press forging followed by full normalizing and tempering (N&T) or isothermal annealing. This carefully controlled heat treatment ensures optimal bainitic or martensitic microstructures that retain high tensile and creep strength up to 600°C.
Available in seamless construction up to 24" NB and welded up to 48" NB across schedules STD, 40, 80, 160, and XXS, all alloy steel fittings conform to ASME B16.9 with 100% NDT inspection and complete EN 10204 Type 3.1 Mill Test Certification.
GM handles enquiries for Alloy 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.
