Scope

Main technical content: This standard specifies the structure, basic requirements, technical requirements, test methods, inspection rules, factory data, marking, coating and transport packaging, and quality commitments of steel coil-wound heat exchangers. This standard is mainly applicable to steel coil-wound heat exchangers used in industries such as petroleum refining, coal chemical, liquefied natural gas, and air separation units. The scope of application complies with Article 1.8 of GB/T 151-2014. The applicable parameter range is: a) Applicable design pressure: not more than 35 MPa; b) Applicable design temperature: not exceeding the allowable use temperature range of the materials listed in GB/T 150.2; c) The nominal diameter of the coil-wound heat exchanger is not more than 6000 mm, and the product of the shell design pressure (MPa) and the nominal diameter (mm) is not more than (4.5×104) MPa?mm. Note: Coil-wound heat exchangers exceeding this range can be manufactured in accordance with this standard.
