T/GDC 12-2018 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 three-layer wall composite reinforced pipes made of polyethylene (PE) and polypropylene (PP) for non-pressure underground applications. This standard is applicable to pipes used for long-term drainage and sewage disposal at temperatures not exceeding 45°C, external drainage of buildings, and agricultural drainage, as well as conduits for communication cables. It can also be used for non-pressure industrial drainage and sewage pipes. Main technical contents: 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 three-layer wall composite reinforced pipes made of polyethylene (PE) and polypropylene (PP) for non-pressure underground applications.
