T/GDC 52-2020 Bare-ground reinforced polyethylene woven pipe with high tensile strength (PP) for buried use
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-strength (PP) reinforced polyethylene wrapped pipes used in underground applications. This standard applies to structural wall pipes made by heat-wrapped molding process, with polyethylene (PE) and polypropylene (PP) resins as the main raw materials, and polypropylene (PP) oriented bent PP special corrugated pipes with isosceles trapezoidal shapes as auxiliary support structures. The pipes specified in this standard are suitable for long-term conveying of media with temperatures below 45°C in underground drainage, sewage disposal, and other projects. Main technical contents: Terms and definitions, symbols, abbreviations, raw materials, pipe grading and marking, pipe structure types and connection methods, technical requirements of high-strength (PP) reinforced polyethylene wrapped pipes.
