T/SCSX 0801-2025 UPE-T double-wall reinforced spiral tube for underground use

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 modified polyolefin (UPE-T) double-wall reinforced winding pipes used in underground applications. This standard applies to double-wall reinforced winding pipes made from modified ultra-high molecular weight polyolefin (UPE-T) resin as the main raw material. The process involves melting and extruding the raw material into trapezoidal strips with a heat-state winding and welding, followed by plastic coating and reinforcement. The pipes are then welded using injection molding machines or manual welding, with anti-slip buckles on the joints. These products feature high ring stiffness, strong shear resistance, good ring flexibility, easy flexible installation, high water flow capacity, good chemical resistance, excellent cold resistance, superior wear resistance, light weight, and cost-effectiveness. The pipes specified in this standard are suitable for long-term transportation of various chemical media and are non-reactive to general weak acids, weak alkalis, and salts. They can be used in non-pressure underground drainage and sewage projects with an environmental temperature range of 40°C to -60°C.
