Scope

This standard specifies the terms and definitions, symbols and abbreviations, materials, classification and marking of structural wall pipes (including pipe fittings) for underground drainage made of polypropylene. It also covers structural types and connection methods, requirements, test methods, inspection rules and marking, transportation, and storage. This standard applies to structural wall pipes and pipe fittings made of polypropylene (PP) as the main raw material, with the same or different plastic materials as auxiliary support structures, and processed using a heat-wrapping molding process. This product is suitable for long-term underground drainage projects with temperatures below 60°C. Under the condition of considering the chemical resistance of the materials, it can also be used in industrial drainage projects.
