GB/T 4732.1-2024

This standard specifies the general requirements for the design-by-analysis methodology of pressure vessels, including material selection, load conditions, and failure mode evaluation. It is applied in the Chinese pressure vessel industry for the design and verification of high-risk or complex vessels, such as those in chemical, petrochemical, and power generation sectors, where traditional design-by-rule approaches are insufficient. The standard ensures safety and reliability through detailed stress analysis and fatigue assessment during the engineering design phase.
