T/ZZB 1663-2020 Centrifugal Casting Glass Fiber Reinforced Plastic Sand-filled Pipes for Trenchless Construction

Scope

Main technical content: This standard specifies the terms and definitions, classification and marking, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, factory certificates and technical documents, and quality commitments for non-excavation construction centrifugally cast fiberglass reinforced plastic sand-filled pipes. This standard applies to centrifugally cast fiberglass reinforced plastic sand-filled pipes with a nominal diameter of 300 mm to 2,400 mm, a pressure rating of 0.1 MPa to 3.2 MPa, and a ring stiffness rating of 1,250 N/m2 and above (hereinafter referred to as centrifugally cast pipes) used in non-excavation construction. The maximum temperature of the transported medium shall not exceed 50 °C. Centrifugally cast pipes with nominal diameters and pressure ratings outside the scope of this standard may also be used as reference.
