Material & Manufacturing Process

Premium Carbon Steel Butt Weld Pipe Fittings | Heavy-Duty Seamless & Welded Industrial Piping Components.

Manufactured in full compliance with ASME B16.9 and EN 10253 standards, our carbon steel butt weld fittings deliver outstanding pressure containment and mechanical strength. Utilizing advanced hot-mandrel push forming, precision cold swaging, hydraulic extrusion, and heavy forging techniques, we process premium certified carbon steel grades. This includes ASTM A234 WPB, WPC, ASTM A105, A350 LF2 Class 1/2 for low-temperature applications, and high-yield line pipe grades like ASTM A860 WPHY42 to WPHY70. Fully compliant with NACE MR0175/ISO 15156 for sour service, all fittings undergo normalized heat treatment, precise CNC end-beveling, and mandatory 100% NDT inspection (UT, RT, MT, PT) to guarantee complete structural integrity.
