GB/T 4732-2024 (Pressure vessels design by analysis - Part 1: General requirements) is available as an English-translated PDF.

GB/T 4732-2024 — 1.1 GB/T 4732 specifies the construction requirements for steel pressure vessels (hereinafter referred to as "vessels") designed using the analytical design method, and provides Design method based on failure mode based on elastic stress analysis or elastoplastic stress analysis.

General requirements for materials, design, manufacture, inspection and acceptance of vessels designed in accordance with this law. 1.2 GB/T 4732 Applicable design pressure. a) Containers with a pressure greater than or equal to 0.1 MPa and less than 100 MPa; b) Containers with a vacuum degree greater than or equal to 0.02MPa.

1.3 The applicable design temperature range of GB/T 4732 is determined according to the applicable temperature range of each part.

1.4 The following containers are not within the scope of application of GB/T 4732. a) Containers with a design pressure less than 0.1 MPa and a vacuum degree less than 0.02 MPa; b) Pressure chambers that are integral or part of rotating or reciprocating mechanical equipment (e.g. pump casings, compressor casings, turbine housings, etc.) housing, hydraulic cylinder, etc.); c) Containers in nuclear power plants that are at risk of failure due to neutron radiation damage; d) direct flame heated vessels; e) Inner diameter (for non-circular cross-sections, it refers to the maximum geometric dimension of the inner boundary of the cross-section.

For example, for a rectangle, it is the diagonal line; for an ellipse, it is the major axis) for 150mm container.
