This part replacesparts ofGB150-1998"SteelPressureVessels(Chapter1~Chapter3,Appendix Band AppendixC)Compared withGB150-1998,this standard has thefollowingmajortechnica changes:
a)Expanded the applicablescope of thestandard.
-By means of reference standards, it is applicable to pressure vessels made of metal materials; -Under the premiseof meeting the design guidelines of this standard, it specifies design
methods to deal with circumstances exceeding standard scopes;
-It specifies the basis Standards for all kinds of structure vessels b)Amendedtherequirements onthequalifications andresponsibilities ofthevessel construction
participants.
-Specifies the storing period for the design documents; -Added the responsibilities of the user or design-trustor in providing the written design
conditions at the design stage;
Specifies the responsibilities of the inspectors from inspection institution on the report
confirmation and testimony of the confirmatory burst test.
c)Amendedthesafetyfactorsfordeterminingallowablestress
Adjustedthesafetyfactoroftensilestrengthfrom3.0to2.7; -Adjustedthe safety factor of yield strength of carbon steels and low-alloy steels fromI.6 to
1.5;
-For austenitic stainless steel, one can use Rpi.o to determine the allowable stress. d)Added conformity declarations tomeetthebasic safetyrequirements prescribed in the safety
technical regulations for special equipment.
e)Added implementationdetailsof thedesignmethods inaddition to adoptive standards and regulations. f) Added the requirements of the risk evaluation at the design stage for pressure vessels and its implementationdetails

GB150-1989,GB150-1998 Introduction
This standard is one of the largegeneral technical standards of pressure vessels developed byand 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 ofthe pressurevesselsconstructedorusedindomainof China.
Thetechnical clauses of thisstandard includethe compulsory requirements,special forbidding requirements andrecommendatoryclausesthat shall befollowedduring the constructionprocess of pressure vessels (namely,design,fabrication, inspection and testing,and acceptance); therecommendatory 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 meettherelevanttechnical requirements inthis 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,butthe engineeringtechnical personnel shall makethe 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 ofthis 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 realizetheanalysis or design of thepressure vessels;ifthe computer programs are adopted for theanalysis or design, not only the requirements ofthis standard shall bemet but also thefollowing items shall be confirmed:
1)Rationality of the technology assumption in the programs adopted; 2)Adaptability ofthe programs adopted to the design contents; 3) Correctness of the input parameters and output results of the programs adopted to the
engineering design.
Inquiryforthetechnical clausesof thestandard shall besubmitted tothecommitteesecretariat 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 committeeis entitledtorefusetheinguiries. The Committee shall not undertakethe responsibility of the understanding ambiguity and any consequencecausedbythestandardpromotionimplementationorexplanationmadebyotherorganizations notauthorizedorapprovedbytheCommitteeinwrittenform.
