This batch of industrial piping components mainly includes 90° long radius elbows and concentric reducers, all manufactured as seamless butt-weld fittings in full compliance with ASME B16.9 specifications. Every A420 WPL6 ASME B16.9 fitting adopts ASTM A420 WPL6 low-temperature carbon steel, a grade widely recognized for reliable toughness in sub-zero pipeline operating conditions, perfectly fitting Malaysia’s petrochemical and energy piping construction standards.
Different from conventional ordinary pipe fittings, this order features ultra-strict chemical element limitation for all A420 WPL6 ASME B16.9 fitting products. We controlled sulfur content below 0.01% and phosphorus content under 0.015%, effectively eliminating brittle fracture risks caused by impurity segregation in low-temperature service. Professional integral heat treatment is implemented for each fitting to stabilize internal microstructure and guarantee consistent long-term mechanical performance.
The delivered A420 WPL6 ASME B16.9 fitting covers multiple practical specifications to meet on-site pipe turning and diameter transition needs. Long radius elbows are available in DN50, DN80 and DN250 sizes with uniform SCH80 wall thickness, while the DN100×DN80 concentric reducer adopts mixed SCH40×SCH80 wall configuration. All fittings are finished with standard black anti-corrosion paint for enhanced outdoor environmental adaptability.
All finished A420 WPL6 ASME B16.9 fitting units are designed with beveled ends for seamless field butt welding, ensuring tight and accurate pipeline assembly. Strict dimensional inspection and chemical composition testing are conducted before shipment, with complete performance reports provided to support on-site project acceptance and long-term operational safety.
Haihao Group specializes in custom low-temperature pipe fittings with strict chemical control standards. We can customize ultra-low sulfur and phosphorus A420 WPL6 fittings with complete heat treatment procedures, providing high-reliability piping solutions for low-temperature industrial projects in Malaysia and Southeast Asia.
