HBIS has supplied 5,700 tons of high-end pipeline steel for the Heihe-Daqing natural gas pipeline project, which forms part of China’s national oil and gas development plan for the 15th Five-Year Plan period.
The project is located in a severe cold-climate region, where the steel must meet demanding requirements for low-temperature toughness, compressive strength, corrosion resistance and weldability.
HBIS said it applied tighter control over rolling, ultrasonic inspection, and temperature-control processes to ensure the supplied material exceeded the required performance standards.
