Pressure vessel

Because the air separation plant is always involved in pressure vessel issue， so the pressure vessel is also one part of air separation plant.
The first article : in order to make sure the safe operation of the pressure vessel and protect  the safety of people’s lives and property and to promote the development of national economy, this code is formulated according to the relevant provisions of the Interim Regulations on safety supervision of boilers and pressure vessels.
The second article: The applicable scope of this procedure is as follows;
This procedure is applicable to pressure vessels with the following conditions
Maximum working pressure (Pw) (note 1) greater than 0.1MPA (no hydrostatic pressure, same below)
Inner diameter (non-circular section refers to its maximum size) is greater than or equal to 0.15m, and volume (V) (note 2) is greater than or equal to 0.25m3;
(The medium is a gaseous liquefied gas or the highest operating temperature is above equal to the standard boiling point liquid.
Chapters III, fourth and fifth of this code apply to the following pressure vessels.
A separate cylinder in a storage tank Boiler room with a non independent volume of a mobile compressor, less than or equal to 0.15m3.
High pressure vessel with volume less than 0.25m3
The cold box of the pressure vessel and the air separation equipment in the pressure vessel, the direct-fired absorption refrigeration unit of the cryogenic unit;
Spiral Plate Heat exchanger
Gas or air pressure water supply (foam) pressure tank for hydraulic automatic air pressure water supply (no tower Sheung Shui) device, air pressure tank in fire extinguishing device.
Pressure vessels for ion exchange or filtration in water treatment equipment, expansion tanks for hot water boilers.
All-closed combined electrical apparatus (capacitor pressure vessel) dedicated to power industry.
Tire vulcanizing machine and pressure rubber mould used in rubber industry.
This procedure is applicable to safety accessories such as safety valve, bursting piece device, emergency shut-off device, safety interlock device, pressure gauge, liquid level meter and temperature meter used in the pressure vessel.
The pressure vessel applicable in this procedure shall include, in addition to the body,
Welded groove of the first circumferential weld to which the pressure vessel is welded with an external pipe or device, the first threaded joint of the threaded connection, the first flange sealing surface of the flange connection, the first sealing surface of a special connecting piece or a pipe fitting.
Pressure vessel openings part of the bearing gland and its fastener
Welded joints of non-pressurized components connected to pressure vessel body.
3rd article This procedure does not apply to the following pressure vessel
Ultra High Pressure vessel
All kinds of gas cylinders.
Pressure vessels made of non-metallic materials.
Nuclear pressure vessels, ships and railway locomotives, ancillary pressure vessels, pressure vessels and pressure vessels working under vacuum (excluding jacket pressure vessels), and various boilers safety technical supervision procedures applicable to the fire-heated equipment (such as flue-type waste heat boilers, etc.) within the scope of application for defense or military equipment.
Normal operation maximum working pressure is less than 0. 1MPA pressure vessel (including in the process of feeding or material to be subjected to instantaneous pressure greater than until 0. 1MPA pressure vessel, excluding disinfection, cooling and other processes in the need for a short time to withstand pressure greater than or equal to 0. 1MPA pressure Vessel).
