Buy SS 347/347H Pipe Fittings & Flanges – Buttweld, Forged & Olets – Engineered for Service in Stress-Rupture & Oxidizing Conditions – Certified to NACE, PED & IBR. As a trusted ISO-certified manufacturer and exporter, we specialize in delivering high-performance piping components in Stainless Steel 347/347H, a stabilized austenitic stainless steel ideal for high-temperature and corrosive environments. Designed with columbium (niobium) for improved stability, SS 347 is widely used in applications where resistance to intergranular corrosion and high-temperature creep strength are critical. We supply a complete range of SS 347H products including Buttweld Fittings, Forged Fittings, Flanges, and Olets, all backed by stringent quality control, timely delivery, and full traceability. Our global supply capability makes us a reliable partner for industries such as oil & gas, petrochemicals, refineries, heat exchangers, and aerospace. Stainless Steel 347H exhibits excellent weldability and high-temperature resistance, especially in environments prone to thermal cycling. Our manufacturing covers all critical standards: ASTM A403 / ASME B16.9 for Buttweld Fittings, ASTM A182 / ASME B16.5 & B16.47 for Flanges, ASTM A182 / ASME B16.11 for Forged Fittings, and ASTM A182 / MSS SP-97 for Olets. We offer buttweld fittings from 1/2” to 48”, forged fittings from 1/8” to 4”, and flanges in 150# to 2500# pressure ratings, up to 24” NB. Each component is supplied with EN 10204 3.1 or 3.2 certification, along with complete MTCs, PMI reports, and third-party inspection support if required. Our Buttweld Fittings in SS 347/347H include long and short radius elbows, concentric/eccentric reducers, tees, stub ends, and end caps – manufactured to meet ASME B16.9 dimensional tolerances. For high-pressure and compact installations, we supply Forged Fittings in Socket Weld and Threaded configurations such as 45°/90° elbows, straight/reducing tees, unions, caps, plugs, and swage nipples as per ASME B16.11.
