T/GDC 12-2019 Unconfined buried polyethylene (PE) / polypropylene (PP) three-layer wall composite reinforced pipe

Scope

Scope: This standard specifies the terms and definitions, symbols, abbreviations, classification, materials, pipe structure and connection methods, technical requirements, test methods, inspection rules and marking, transportation, and storage of non-pressure buried polyethylene (PE)/polypropylene (PP) three-wall composite reinforced pipes. This standard applies to non-pressure municipal buried pipes for drainage, sewage disposal, building exterior drainage, and farmland drainage with a long-term temperature not exceeding 45°C, as well as conduits for communication cables. It can also be used for non-pressure buried industrial drainage and sewage pipes. Main technical content: raw materials, recycled materials, elastic sealing rings, product grading and marking, pipe structure and connection methods, color, appearance, specifications and dimensions, pipe length, dimensions, physical and mechanical performance requirements, and sealing performance during pipe connection of non-pressure buried polyethylene (PE)/polypropylene (PP) three-wall composite reinforced pipes.
