1.1 This standard specifies the design, manufacturing, testing, acceptance, storage, installation as well as basic parameters and dimensions of metal bellows expansion joint (hereinafter referred to as "expansion joint"). 1.2 This standard is applicable to the non-reinforced monolayer or multilayer U-shaped expansion joints for steel pressure vessels, steel tubular heat exchangers and atmospheric vessels. The expansion joints in pipelines also may be made reference to this standard. 1.3 For the expansion joints to which this standard is applicable, the design pressure shall not be larger than 6.4 MPa, and the design temperature scope shall be determined according to the allowable service temperature of steel products. 1.4 This standard is not applicable to the expansion joints for the direct fired pressure vessels.
