range of the materials listed in GB 150.2
1.3.3 For vessels made of other metal materials, the design temperature shall be detennined according
to the allowable operating temperature of the materials listed in the coiTesponding reference standards
ofThis pa1t.
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 1 50.4.
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 473 1 "Steel Horizontal Vessels on Saddle Suppo1t";

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 O.lMPa and vacuuh1 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, hydrau lic cylinders etc.) which can be its own system or as components in
swiveli ng or reciprocating movement machinery;
d) Vessels subject to the neutron radiation damage fai lure 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 gitth joints with welded connection;
b) The fi rst threaded connector end surface of screwed joint;
c) The sealing surface of the first flange with flanged connection;
d) The fu·st 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-pressw-e components and pressure components.
1.6.4 Non-pressure components such as supp01t and skitt directly connected to the vessels.
1.6.5 Excessjve pressure rei ief device of vessel (see Appendix B).

Risk Assessment Report
F.l General P rovisions
F.l.l This Appendix specifies the basic requirements for the risk assessment repott.
F.1.2 The vessel designers shall draw up a Risk Assessment Report aiming at the expected vessel
service conditions according to the relevant laws and regulations or the requirements of the design-
trustor.
F.l.3 The designers shall give full consideration to the possible failure modes under a variety of
working conditions, put forward safety measures on the issues such as material selection, structural
design, fabrication inspection requirements and other aspects, to prevent any possible failure.
F.1.4 The designers shall provide the vessel users with any required information to draw up emergency
plans for vessel incidents.
F.2 Principles and P rocedures of Report Formulation
F.2.1 At the design stage, the risk assessment is mainly aimed at hazard identification and risk
control.
F.2.2 At the design stage, the risk assessment shall be conducted according to the following
procedures.
a) On the basis of the user design conditions and other design input information, to determine
the various use conditions of the vessel;
b) On the basis of the medium, operating conditions and environmental factors in various use
conditions to caJTy out hazard identification, to determine any possible hazards and consequences;
c) Contrary to all hazards and corresponding failure modes, to explain all safety protection
measures and evidences shall be taken;
d) With regard to all possible failure modes, provide the required information to draw up
emergency plans;
e) Form a complete risk assessment report.
F.3 Contents of Risk Assessment Report
A risk assessment report shall at least include.
a) The basic design parameters of pressure vessel. pressure, temperature, materials, medium
properties and external loads, etc.;
b) Description of the operating conditions;
c) Possible hazards under a ll the operation and design conditions, such as. explosions, leakage,
breakage, deformation, etc.;
d) For the failure modes have been specified in standards, illustrating the tenus of that standard;
e) For the failure modes have not been specified in standards, illustrating the selection basis of
the design loads, safety factors and the corresponding calculation methods;
t) Measures on how to deal with small amount leakages and large amount emissions of medium
and explosive situations;
g) Specify appropriate personnel protective equipment and measures according to possible il"Uury
situation of surrounding personnel;
h) The risk assessment repo11 shall have consistent signatures as the design drawings.
