This standard is one of the large general technical standards of pressure vessels developed by and under the jurisdiction of the National Technical Committee on Boilers and Pressure Vessels of Standardization Administration of China (hereinafter referred to as "Committee"), to specify the technical requirements related to the design, fabrication, inspection and testing, and acceptance of the pressure vessels constructed or used in domain of China.
The technical clauses of this standard include the compulsory requirements, special forbidding requirements and recommendatory clauses that shall be followed during the construction process of pressure vessels (namely, design, fabrication, inspection and testing, and acceptance); the recommendatory clauses thereof are not compulsory parts. As it is unnecessary and impossible for this standard to include all the technical details during the construction process of pressure vessels within the application scope, under the premise of meeting the basic safety requirements specified in the laws and regulations, the technical contents not specially mentioned in this standard shall not be prohibited. This standard cannot be used as the technical manual for the specific pressure vessels construction, or replace the training, engineering experience and engineering evaluation. Engineering evaluation is the specific-product-oriented technology evaluation made by the knowledgeable and experienced technical personnel. However, the engineering evaluation shall meet the relevant technical requirements in this standard and shall not violate the compulsory requirements and forbidding requirements in this standard.
This standard does not restrict the state-of-the-art technical methods adopted during the actual engineering design and construction process, but the engineering technical personnel shall make the reliable judgment when adopting the state-of-the-art technical methods to ensure that they meet the requirements of this standard, especially the compulsory design requirements (such as strength or stability design formula).
The technical methods and technical requirements specified in this standard are not involved with any patent. Please note that the engineering applications of this standard may involve specific patents; the issuance organization of this standard shall not undertake the responsibility of identifying these patents.
This standard does not specify nor prohibit the designing personnel by using the computer programs to realize the analysis or design of the pressure vessels; if the computer programs are adopted for the analysis or design, not only the requirements of this standard shall be met but also the following items shall be confirmed:
1) Rationality of the technology assumption in the programs adopted;
2) Adaptability of the programs adopted to the design contents;
3) Correctness of the input parameters and output results of the programs adopted to the engineering design.
Inquiry for the technical clauses of the standard shall be submitted to the committee secretariat in written form, so shall the necessary information. All the inquiries which are not related to standard clauses directly or which cannot be understood are deemed as technical consultation. As a result, the committee is entitled to refuse the inquiries.
The Committee shall not undertake the responsibility of the understanding ambiguity and any consequence caused by the standard promotion implementation or explanation made by other organizations not authorized or approved by the Committee in written form.
GB 150 "Pressure Vessels" comprises the following four parts: ——Part 1: general requirements; ——Part 2: Materials; ——Part 3: Design; ——Part 4: Fabrication, Inspection and Testing, and Acceptance.
