Application Summary AI generated
GB/T 21237-2007 specifies the technical requirements for wide and heavy steel plates used in the manufacture of longitudinally or spirally welded pipes for transporting petroleum and natural gas. It is applied in the oil and gas pipeline industry, particularly for high-pressure transmission lines requiring strict control of mechanical properties, dimensional tolerances, and weldability. The standard ensures these plates meet safety and performance criteria for buried or above-ground pipeline systems in demanding environments.
