ISO Certified Supplier of ASTM A234 WP1/WP5/WP9/WP11/WP22/WP91 Pipe Fittings – All Schedules & Sizes . ASTM A234 WP1, WP5, WP9, WP11, WP22, and WP91 are specifications for Chrome Moly (Cr-Mo) alloy steel buttweld pipe fittings, designed for use in pressure piping and high-temperature services. These low-alloy steels, enriched with chromium and molybdenum, offer superior mechanical strength, thermal resistance, and corrosion protection compared to carbon steel. These grades are ideal for critical applications in oil & gas pipelines, thermal power plants, petrochemical facilities, and refinery units, where exposure to high temperatures, aggressive media, and stress conditions is common. We stock and manufacture a complete range of ASTM A234 alloy steel pipe fittings across all mentioned grades, including 90° and 45° elbows, equal/reducing tees, concentric/eccentric reducers, end caps, and stub ends. These fittings are available in both seamless and welded constructions, produced in compliance with ASME B16.9, MSS SP-43, and ANSI B36.10 standards. Sizes range from ½” NB to 36” NB, with wall thicknesses from SCH 10 to SCH XXS. Each grade is either normalized, tempered, or annealed based on specific service requirements to ensure long-term structural integrity. All our A234 fittings are manufactured under a stringent ISO 9001:2015-certified quality system and are subjected to rigorous quality control checks including PMI testing, hydrostatic testing, ultrasonic inspection, and dimensional verification. Products are supplied with complete EN 10204 3.1/3.2 MTCs, and third-party inspection (TPI) from agencies like BV, Lloyds, SGS, and TUV is available upon request. With global stock points and export-ready inventory, we cater to urgent project needs and shutdown requirements across Asia, the Middle East, Europe, and Africa.
