T/JXSYHG 001-2021 HDPE Nano-lined Square Reinforced Pipe

Scope

Scope: This standard specifies the terms and definitions, symbols, abbreviations, raw materials, classification and marking, structure and connection methods, technical requirements, test methods, inspection rules, marking, transportation, and storage of HDPE nano-lined square reinforced pipes. This standard applies to structural wall pipes made by winding molding process using high-density polyethylene (HDPE) resin as the main raw material and square-shaped HDPE oriented curved corrugated pipes as the auxiliary support structure. The pipes specified in this standard are suitable for long-term working temperatures below 45°C in underground drainage, sewage disposal, and other projects. Main technical content: Using high-density polyethylene (HDPE) resin as the main raw material, adding ultra-high molecular weight copolymer compatibilizers, nano-reinforcing agents, and special anti-aging additives, etc., and using square-shaped HDPE oriented curved corrugated pipes as the auxiliary support structure, the structural wall pipes are made by winding molding process after processing.
