Basic Information
Scope
Main technical content: This document specifies the terms and definitions, classification and marking, basic requirements, technical requirements, test methods, inspection rules, marking, installation lines, packaging, transportation and lifting, storage, and quality commitments for continuous-wound glass fiber reinforced plastic sand-filled pipes (hereinafter referred to as CWFP pipes). This document is applicable to CWFP pipes with a nominal diameter of 200 mm to 4,000 mm, a pressure rating of 0.1 MPa to 3.2 MPa, a ring stiffness rating of 1,250 N/m2 to 10,000 N/m2, and a maximum medium temperature of not more than 50 °C, used in piping projects such as water supply and drainage, water conservancy, and farmland irrigation. Continuous-wound glass fiber reinforced plastic pipes without sand filling may also refer to this document for use.
