T/CISA 108-2021 Corrosion-resistant flexible jointing pipe for drainage purposes
Basic Information
Scope
Scope: This document is applicable to pipes with a nominal diameter of DN150 to DN1600, a water temperature not exceeding 45℃, and a maximum design pressure of 2.5 MPa when DN exceeds 500, or 3.0 MPa when DN is less than or equal to 500, used in building water supply and drainage, municipal water supply and drainage, water conservancy projects, etc. The inner and outer surfaces of these pipes are generally corrosion-resistant and equipped with socket-and-spigot flexible joints; Main technical contents: This document specifies the terms and definitions, symbols and abbreviations, order content, joint type, pressure grade, dimensions, sealing ring, weight, appearance, technical requirements, test methods, inspection rules, marking, packaging, and quality certificates for socket-and-spigot flexible joint anti-corrosion steel pipes used in water supply and drainage.
