ISO Certified Stockist of ASTM A860 WPHY 42/46/52/60/65/70 High-Yield Carbon Steel Fittings – Seamless & Welded - Buttweld Elbows, Tees, Reducers– Full Range of Schedules & Sizes Ready for Dispatch.
We are an ISO 9001:2015 certified manufacturer and exporter of high-performance pipe fittings, specializing in ASTM A860 WPHY 42 to 70 grades. Backed by years of industry experience, we offer a complete range of buttweld pipe fittings including elbows, tees, reducers, caps, crosses, and stub ends. These fittings are manufactured with precision engineering to meet demanding specifications in oil & gas, offshore, petrochemical, and power sectors. With robust inventory and efficient logistics, we ensure rapid delivery to both domestic and international clients.
ASTM A860 WPHY (Wrought Pipe High-Yield) grades such as 42, 46, 52, 60, 65, and 70 are produced using high-strength low-alloy (HSLA) steel, conforming to standards like ASME B16.9, MSS SP-75, and ANSI/ASME B36.10M. These fittings are available in sizes from ½” NB to 48” NB, with wall thickness ranging from SCH 10 to XXS. Products can be supplied in seamless or welded construction with bevel ends or plain ends as per customer requirements. All fittings undergo NDT, hydro testing, and third-party inspection as per project specifications.
WPHY fittings are primarily used in high-pressure transmission pipelines, natural gas processing, onshore/offshore facilities, refineries, and chemical plants. These grades are preferred for critical operations that demand high yield strength, excellent impact resistance, and long-term reliability under stress. The A860 WPHY series supports structural integrity in both standard and sour service environments, and are often used in conjunction with API line pipe systems (e.g., API 5L X60, X65).
Our fittings offer exceptional mechanical strength, dimensional precision, and corrosion resistance. Key benefits include high yield-to-tensile ratio, superior weldability, and excellent pressure handling capacity. We provide full documentation, including Mill Test Certificates (MTCs), NACE compliance, IBR approval, and third-party inspection reports. All products are securely packed for global delivery and dispatched with customs-ready export documentation, making us a trusted partner for clients worldwide.
