Basic Information
Scope
Scope: This standard specifies the terms and definitions, symbols, abbreviations, raw materials, pipe grading and marking, pipe structure types and connection methods, technical requirements, test methods, inspection rules and markings, transportation and storage for high-density polyethylene (HDPE) winding reinforced pipes connected by throttling fittings and elastic sealing rings using the winding molding process as the main raw material. This standard applies to structural wall pipes made from HDPE as the main raw material, connected by throttling fittings and elastic sealing rings, and processed using the winding molding process. The pipes specified in this standard are suitable for long-term conveying of media with a temperature below 45°C in underground drainage and sewage projects; Main technical content: 1. Pipe structure types and connection methods; 2. Technical requirements: color, appearance, specifications, physical and mechanical properties, and system applicability.
