Pressure vessel plates adhere to region-specific technical standards ensuring safety and performance under extreme conditions. Key international benchmarks include:

GB/T713-2014 (China): Mandatory for domestic projects, covering grades like Q245R (245MPa yield) and Q345R (345MPa yield), with strict controls on impurities (S/P≤0.025%) and mandatory ultrasonic testing for critical applications.

ASME SA-516 (USA): Globally recognized for moderate-to-low temperature services (-29°C to 343°C), with Grades 60/70 matching Q245R/Q345R mechanical properties but differing in trace element limits.

EN 10028-3 (EU): Governs P-series steels like P265GH and P355GH, emphasizing elevated temperature tensile strength (tested at 50°C above design temp) and Charpy impact values at -20°C.

JIS G3115 (Japan): Defines SPV series plates (e.g., SPV355) with unique notch toughness requirements for seismic-prone regions.

Our dual-certified plates (e.g., Q345R with ASME/EN cross-approvals) streamline global procurement, offering chemical composition harmonization and compliance documentation (EN 10204 3.1/3.2). Critical differences lie in testing protocols: ASME prioritizes tensile strength at room temperature, while EN standards mandate prolonged stress rupture testing for hydrogen service.
