Book excerpt: 1.1 This standard specifies the construction requirements of metal pressure vessels (hereinafter referred to as "Vessels"). This standard specifies the general requirements for the materials, design, fabrication, inspection and testing, and acceptance of metal pressure vessels (hereinafter referred to as “Vessels”). 1.2 Applicable design pressure of this Standard 1.2.1 For steel vessels, the design pressure shall not exceed 35MPa; 1.2.2 For vessels made of other metal materials, the applicable design pressure shall be determined according to the corresponding reference standards. 1.3 Applicable design temperature range of this Standard 1.3.1 Design temperature range: -269℃~900℃. 1.3.2 For steel vessels, the design temperature shall not exceed the allowable operating temperature range of the materials listed in GB 150.2 1.3.3 For vessels made of other metal materials, the design temperature shall be determined according to the allowable operating temperature of the materials listed in the corresponding reference standards of this Part. 1.4 Applicable structure forms of this Standard 1.4.1 The structure forms of the steel vessels to which this Standard is applicable shall be in accordance with the corresponding provisions of this Part and GB 150.2 ~ GB 150.4. 1.4.2 As for the vessels with specific structures and the vessels made of aluminum, titanium, copper, nickel and nickel alloy, as well as zirconium to which this Standard is applicable, the structure forms and applicable scope shall meet the corresponding requirements of the following standards: a) GB 151 Tubular Heat Exchangers; b) GB 12337 Steel Spherical Tanks; c) JB/T 4731 Steel Horizontal Vessels on Saddle Support; d) JB/T 4710 Steel Vertical Vessels Supported by Skirt; e) JB/T 4734 Aluminim Welded Vessels; f) JB/T 4745 Titanium Welded Vessels; g) JB/T 4755 Copper Pressure Vessels; h) JB/T 4756 Nickel and Nickel Alloy Pressure Vessels; i) NB/T 47011 Zirconium Pressure Vessels. 1.5 The following vessels are not within the applicable scope of this Standard: a) Vessels with design pressure lower than 0.1MPa and vacuum degree lower than 0.02MPa; b) Vessels under "Supervision Regulation on Safety Technology for Transportable Pressure Vessel"; c) Among equipment, the pressure chambers (such as pump casing, outer casing of compressors, outer casing of turbines, hydraulic cylinders etc.) which can be its own system or as components in swiveling or reciprocating movement machinery; d) Vessels subject to the neutron radiation damage failure risk in nuclear power plants. e) Vessels heated by direct flame; f) Vessels with inner diameter (for non-circular sections, refers to the maximum geometric dimensions of the inner boundaries of the sections, such as: diagonals of rectangles and major axes of ellipses) less than 150mm; g) Enamelled vessels and the vessels with other national standards or professional standards in the refrigeration and air conditioning industry. 1.6 Vessels scope 1.6.1 Connection between the vessel and the external pipe: a) The groove end face of the first pass of girth joints with welded connection; b) The first threaded connector end surface of screwed joint; c) The sealing surface of the first flange with flanged connection; d) The first sealing surface of special connecting piece or pipe fittings connection. 1.6.2 Bearing headers, flat covers and their fasteners of connection pipe, manhole and handhole, etc. 1.6.3 Attachment welds between non-pressure components and pressure components. 1.6.4 Non-pressure components such as support and skirt directly connected to the vessels. 1.6.5 Excessive pressure relief device of vessel (see Appendix B).
