TSG 21-2016 Supervision Regulation on Safety Technology for Stationary Pressure Vessel

Scope

This regulation applies to pressure vessels defined in the Special Equipment Catalogue that meet the following conditions: (1) working pressure greater than or equal to 0.1 MPa (Note 1-2); (2) volume greater than or equal to 0.03 m3 and an inner diameter (for non-circular sections, the maximum geometric dimension of the inner boundary) greater than or equal to 150 mm (Note 1-3); (3) the medium contained is gas, liquefied gas, or a liquid with a maximum working temperature equal to or greater than its standard boiling point (Note 1-4). This regulation does not apply to the following vessels: (1) mobile pressure vessels, gas cylinders, and oxygen chambers; (2) military equipment, nuclear facilities, aerospace vehicles, railway locomotives, offshore facilities, and ships, as well as pressure vessels used in underground mines; (3) containers with a normal operating working pressure less than 0.1 MPa (including those connected to the atmosphere that need to withstand instantaneous pressures equal to or greater than 0.1 MPa during feeding or discharging); (4) pressurized chambers integrated as a whole or as components in rotating or reciprocating mechanical equipment (such as pump housings, compressor housings, turbine housings, hydraulic cylinders, papermaking rollers, etc.); (5) plate heat exchangers, spiral plate heat exchangers, air-cooled heat exchangers, and cooling fin tubes; (6) steam heating coils in atmospheric pressure vessels and tubular heating furnaces in process equipment; (7) fully enclosed switchgear dedicated to the power industry (such as capacitor pressure vessels); (8) tire vulcanizers and pressurized rubber molds used in the rubber industry; (9) unreinforced plastic pressure vessels.
