This standard specifies the terms and definitions, materials, requirements, test methods, inspection rules and markings, packaging, transportation and storage of steel-plastic composite and plastic short-pitch internal spiral pipes for building drainage. This standard applies to steel-plastic composite and plastic short-pitch internal-pitch pipes for civil building drainage system risers. The operating temperature of the drainage system varies with the lining layer and plastic material: rigid polyvinyl chloride (PVC-U) material is suitable for water temperatures of 0℃~45℃, and the instantaneous drainage temperature does not exceed 60℃; high-density polyvinyl chloride (HDPE) And polypropylene (PP) material is suitable for water temperature 0 ℃ ~ 65 ℃, and the instantaneous drainage temperature does not exceed 90 ℃.
