T/SITA 100-2025 Multicomponent blended plastic inner-reinforced pipes for sewage and drainage

Scope

This document applies to underground sewage and drainage pipes made of extruded mixtures of modified nylon-reinforced perchlorinated polyethylene and polyvinyl chloride, mainly used in municipal engineering, outdoor public buildings, residential communities, as well as agricultural irrigation projects with a nominal pressure ≤ 0.2 MPa and low-pressure drainage pipes. Note: If the pipes are used for industrial sewage and drainage, the chemical resistance of the materials should be considered. For the evaluation of chemical resistance, refer to ISO 4433-1 and ISO 4433-3. This document specifies the terms, definitions, and symbols, materials, classification, structural types and connection methods, requirements, test methods, inspection rules, and marking for multi-component co-extruded plastic pipes reinforced with inner ribs (hereinafter referred to as pipes) used for sewage and drainage.
