Haihao Group Delivers ASTM A420 WPL6 Low-Temperature Fittings and A333 Gr.6 Pipes to Russia

Haihao Group has recently completed a shipment of ASTM A420 WPL6 low-temperature fittings and ASTM A333 Grade 6 seamless pipes for a major client in Russia. These products are specifically engineered for pipeline systems operating in low-temperature and high-pressure environments, where material reliability and dimensional accuracy are essential.

The order includes a wide range of elbows, tees, reducers, and caps manufactured under strict compliance with ASTM and ASME standards. The matching A333 Gr.6 seamless pipes were produced with meticulous attention to chemical composition, mechanical strength, and impact performance at sub-zero temperatures. Each item underwent rigorous non-destructive testing (NDT) and hydrostatic inspection to ensure superior quality and consistency before shipment.

Russia’s climate poses significant challenges for pipeline materials. In such conditions, ASTM A420 WPL6 and A333 Gr.6 steels are preferred for their exceptional toughness, weldability, and impact resistance at temperatures as low as −45°C. These properties make them ideal for use in oil and gas transmission lines, liquefied natural gas (LNG) facilities, and refinery applications where safety and reliability are paramount.

Haihao Group’s engineering and quality control teams worked closely with the client throughout production – from material selection to final inspection and packaging. The entire process was carried out according to international standards to guarantee that every fitting and pipe meets both technical and operational requirements.
