1.0.2 This standard is used for the selection and installation of metal pipes and flow compensators for the import and export pipes of the normal pressure vertical four-type steel energy storage system (hereinafter referred to as the energy storage system) with a fire resistance of 6-3 degrees (hereinafter referred to as 6-9 degrees) 1. The metal pipes and flow compensators selected and installed in accordance with this standard may suffer slight damage when they are affected by the local fire of the intensity set, but will not cause serious secondary fire damage.
1.The anti-intensity installation should be based on the national standards and the market approval, and the additional documents (drawings) issued should determine the required cost under virtual conditions; for areas where ground installation has been done or ground shadow planning has been carried out, the approved basic sensitivity of the ground bag should be used as the basis for planning and expansion.
1.5 When selecting and installing metal hoses or wave effect compensators according to wooden standards, they should also comply with the requirements of the current relevant product standards and implementation acceptance specifications. 1.6 Body: Doors, piping systems and related transformers (structures) should comply with the design specifications of various industries before installation. 2.1 Terminology or symbols 2.2.1 Terminology 2.2.2.1 Corrugated tube: corrugated tube. The corrugated tube is a corrugated tube with a corrugated shape, a flexible screen arm and a corrugated compensator. 2.1.2 Corrugated tube surface is a corrugated tube with a flexible surface. 2.2.2.1 Corrugated tube surface is a corrugated tube with a flexible surface. tings

3.1J Enterprises use the two-mouth flange of the effective pipe, and the structure with the external mesh is shown in Figure 2.1
7.1.2 The effective compensator should use the horizontal mesh structure (see Figure 2.1.5] 1.1.3 The flexible hose or the wave effect compensation should use the flange of 1.EMP pressure version. When the nominal diameter is not more than 600mm, the flat steel flange is used. The B-shaped welded loose flange can also be used according to the user. The user needs to adopt other connection methods: when the nominal diameter is greater than 600mm, the connection method at both ends shall be determined according to the application requirements.
3.2 Product specifications
3.2.1 Product specifications include nominal diameter, nominal end length, and three parameters. 3.2.2 The specifications and corresponding maximum displacement of the compensator shall meet the requirements in Table 3.2.2.
3.2.3 The specifications and corresponding maximum displacement of the compensator shall meet the requirements in Table 3.2.3. 3.3 Technical requirements 3.3.1 The nominal pressure of the self-wave effect compensator of the network hose shall be 1.0MPa 3.3.2 In addition to the expansion resistance and inspection rules, the hose shall comply with the relevant provisions of GB/T4525 "General Technical Requirements for Corrugated Metal Pipes". 3.3.3 In addition to the inspection rules for the shock resistance and integrity of the compensator, the hose shall comply with the relevant provisions of GB/T4525 "General Technical Requirements for Corrugated Metal Pipes". 3.3.4 In addition to the inspection rules for the shock resistance and integrity of the compensator, the hose shall comply with the relevant provisions of GB/T4525 "General Technical Requirements for Corrugated Metal Pipes". 3.3 .4.1 Axial tensile strength and resistance
