It also \u003cbr\u003especifies the requirements for materials, design, manufacture, inspection, acceptance, \u003cbr\u003einstallation, and use of shell-and-tube heat exchangers. \u003cbr\u003e1.2 The general requirements of this document apply to shell-and-tube heat exchangers \u003cbr\u003eand other types of heat exchangers. All contents of this document apply to shell-and- \u003cbr\u003etube heat exchangers. \u003cbr\u003e1.3 The design pressure applicable to this document is. \u003cbr\u003ea) The design pressure of shell-and-tube heat exchangers shall not exceed 35 MPa; \u003cbr\u003eb) The design pressure of other types of heat exchangers shall be determined in \u003cbr\u003eaccordance with the relevant referenced product standards. \u003cbr\u003e1.4 The design temperature applicable to this document is. \u003cbr\u003ea) The design temperature range for steel heat exchangers shall be in accordance \u003cbr\u003ewith the allowable operating temperature range for materials listed in GB\/T \u003cbr\u003e150.2-2024; \u003cbr\u003eb) The design temperature of non-ferrous metal heat exchangers shall be determined \u003cbr\u003eaccording to the allowable operating temperature of the materials listed in the \u003cbr\u003erelevant referenced standards. \u003cbr\u003e1.5 This document applies to shell-and-tube heat exchangers where the product of the \u003cbr\u003edesign pressure (MPa) and nominal diameter (mm) is not greater than 4.05 × 10⁴. For \u003cbr\u003enon-removable tube bundle shell-and-tube heat exchangers, the nominal diameter is not \u003cbr\u003egreater than 6000 mm. For removable tube bundle shell-and-tube heat exchangers, the \u003cbr\u003enominal diameter is not greater than 2600 mm. \u003cbr\u003e1.6 Shell-and-tube heat exchangers exceeding the range of 1.5 shall be constructed in \u003cbr\u003eaccordance with this document. \u003cbr\u003e1.7 This document does not apply to the following heat exchangers. \u003cbr\u003ea) Heat exchangers heated by direct flame; \u003cbr\u003eb) Flue-type waste heat boilers; \u003cbr\u003ec) Heat exchangers in nuclear power plants that pose a risk of failure due to neutron \u003cbr\u003eradiation damage; \u003cbr\u003ed) Non-metallic heat exchangers; \u003cbr\u003ee) Heat exchangers for which there are separate national or industry standards in the \u003cbr\u003erefrigeration and air conditioning industry. \u003cbr\u003e1.8 The scope of heat exchangers is defined as follows. \u003cbr\u003ea) Heat exchanger connection to external tubing. \u003cbr\u003e1) The first bevel face of a welded joint; \u003cbr\u003e2) The first threaded joint face of a threaded joint; \u003cbr\u003e3) The first flange sealing face of a flange joint; \u003cbr\u003e4) The first sealing face of a special connector or fitting connection. \u003cbr\u003eb) Pressure-bearing heads, flat covers, and their fasteners for tubes, manholes, \u003cbr\u003ehandholes, etc. \u003cbr\u003ec) Welds connecting non-pressure-bearing components to pressure-bearing \u003cbr\u003ecomponents. \u003cbr\u003ed) Non-pressure-bearing components directly connected to the heat exchanger, such \u003cbr\u003eas supports and gaskets. \u003cbr\u003ee) Overpressure relief devices installed on the heat exchanger. \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eBasic Data\u003c\/h2\u003e\n\u003ctable id=\"TableTabAbout0\" border=\"1\" style=\"font-family: Arial; font-size: Small;\"\u003e\n\u003ctbody\u003e\n\u003ctr id=\"TableTabRow10\"\u003e\n\u003ctd id=\"TableTabCell110\" align=\"center\"\u003e\u003cb\u003eStandard ID\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd id=\"TableTabCell120\" align=\"center\"\u003eGB\/T 151-2026 (GB\/T151-2026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr id=\"TableTabRow20\"\u003e\n\u003ctd id=\"TableTabCell210\" align=\"center\"\u003e\u003cb\u003eDescription (Translated English)\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd id=\"TableTabCell220\" align=\"center\"\u003eHeat exchangers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr id=\"TableTabRow30\"\u003e\n\u003ctd id=\"TableTabCell310\" align=\"center\"\u003e\u003cb\u003eSector \/ Industry\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd id=\"TableTabCell320\" align=\"center\"\u003eNational Standard (Recommended)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr id=\"TableTabRow40\"\u003e\n\u003ctd id=\"TableTabCell410\" align=\"center\"\u003e\u003cb\u003eClassification of Chinese Standard\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd id=\"TableTabCell420\" align=\"center\"\u003eJ75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr id=\"TableTabRow50\"\u003e\n\u003ctd id=\"TableTabCell510\" align=\"center\"\u003e\u003cb\u003eClassification of International Standard\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd id=\"TableTabCell520\" align=\"center\"\u003e71.120.30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr id=\"TableTabRow60\"\u003e\n\u003ctd id=\"TableTabCell610\" align=\"center\"\u003e\u003cb\u003eDate of Issue\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd id=\"TableTabCell620\" align=\"center\"\u003e2026-01-28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr id=\"TableTabRow70\"\u003e\n\u003ctd id=\"TableTabCell710\" align=\"center\"\u003e\u003cb\u003eDate of Implementation\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd id=\"TableTabCell720\" align=\"center\"\u003e2026-08-01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr id=\"TableTabRow80\"\u003e\n\u003ctd id=\"TableTabCell810\" align=\"center\"\u003e\u003cb\u003eOlder Standard (superseded by this standard)\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd id=\"TableTabCell820\" align=\"center\"\u003eGB\/T 151-2014\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"www.ChineseStandard.us -- Field Test Asia Pte.
