Scope

This document specifies the definition, symbols and abbreviations, materials, pipe structure and connection methods, technical requirements, test methods, inspection rules, marking, transportation, and storage of assembled winding structural wall pipes. This document applies to nanomodified high-density polyethylene (HDPE) pipes for underground use, which are produced by adding appropriate amounts of inorganic nanoparticles, light stabilizers, lubricants, colorants, etc. to HDPE resin, followed by high-temperature blending modification and unique molding processes (hereinafter referred to as "MUHDPE-PANS winding structural wall pipes"). This document is suitable for underground drainage and sewage projects with a long-term working temperature below 45°C, and is mainly used in municipal engineering, transportation facilities, agriculture, and water conservancy construction fields. This document specifies the definition, symbols and abbreviations, materials, pipe structure and connection methods, technical requirements, test methods, inspection rules, marking, transportation, and storage of assembled winding structural wall pipes.
