2. Description

GB/T 5310 Seamless Steel Pipes for High-Pressure Boilers

GB/T 5310 is a Chinese national standard for high-temperature and high-pressure seamless steel pipes, widely used in power plant boilers, superheaters, reheaters, and high-pressure pipelines. These pipes are designed to withstand extreme thermal and mechanical stress, ensuring reliability in critical applications.

Key Features & Applications:
 High-Temperature Resistance - Suitable for steam boilers (up to 610°C).
 Pressure Endurance - Ideal for power plants, petrochemical, and thermal energy systems.
 Material Versatility - Available in carbon steel (20G), Cr-Mo alloy (15CrMoG, 12Cr1MoVG), and advanced heat-resistant grades (T91).
 Global Equivalents - Complies with ASTM (SA-106, SA-335), DIN 17175, and EN 10216-2/5 standards for international compatibility.

Industries: Power generation, oil & gas, chemical processing, and heavy machinery.
