Scope

Main technical content: This standard specifies the terms and definitions, symbols and abbreviations, materials, pipe classification and marking, structural types and connection methods, basic requirements, technical requirements, test methods, inspection rules, marking, transportation and storage, and quality commitments of UV-resistant and crack-resistant polyethylene hollow double-walled spiral pipes (hereinafter referred to as "pipes"). This standard applies to structural wall pipes with smooth inner and outer walls, which are made from polyethylene (PE) compound materials by using the spiral winding molding process. These pipes are suitable for long-term temperature below 45 °C applications, such as drainage, sewage treatment, and irrigation in agricultural fields. They can be used underground and, under certain conditions, can be stored and used outdoors.
