T/GDC 28-2019 High-performance polyvinyl chloride/polyethylene fiber-reinforced woven tube

Scope

Scope: This standard specifies the classification and marking of high-performance polyvinyl chloride/polyethylene fiber-reinforced winding pipes (hereinafter referred to as winding pipes), as well as their connection methods, raw materials, requirements, test methods, inspection rules, marking, transportation, and storage. This standard applies to pipes/culverts with a nominal diameter of 300mm–4000mm and a pressure rating of ≤1kg, which are mainly used in municipal drainage, sewage disposal, and wastewater discharge from chemical plants (with a temperature range of ≤45°C) on the ground and underground, as well as in unpressurized water conveyance in agricultural fields. They are made of high-performance polyvinyl chloride/polyethylene as the inner lining, unsaturated polyester as the matrix, and glass fiber yarn or fiber cloth fabric as the reinforcing material. Main technical contents: appearance quality, dimensional specifications, Barcol hardness, content of non-soluble resin, content of wall components in straight pipes, physical and mechanical properties, process requirements, and rubber seals for joints.
