T/CPPIA 43-2024 Stainless steel belt-reinforced polyethylene (PE) spiral corrugated pipe

Scope

Scope: This document specifies the terms and definitions, symbols, abbreviations, raw materials, grading and marking, pipe structure and connection methods, requirements, test methods, inspection rules, marking, transportation and storage for stainless steel tape-reinforced polyethylene (PE) spiral corrugated pipes. This document is applicable to non-pressure underground drainage pipes for conveying media with a temperature not exceeding 45°C, such as rainwater and sewage. Main technical content: 7. Requirements 7.1 Color 7.1.1 The outer layer of the pipe should be black, and the inner layer should be blue or yellow, with a uniform color. 7.1.2 When using other colors, it can be negotiated between the supplier and the buyer. 7.2 Appearance 7.2.1 The inner surface of the pipe should be smooth and flat, and the outer corrugation should be regular. There should be no bubbles, cracks, or visible impurities on the inner and outer walls of the pipe. 7.2.2 When the pipe uses a spiral port, the cut should be selected at the trough of the pipe without stainless steel tape, and the two ends of the cut should be on the same longitudinal line of the pipe. 7.2.3 When the pipe uses a flat port, the cut should be perpendicular to the pipe axis. 7.2.4 After cutting, the cross-section of the pipe should be trimmed without burrs. The pipe ports and cavity parts should be sealed with polyethylene strips to block the cut parts, and the stainless steel tape should not be exposed. 7.3 Specifications and dimensions 7.3.1 Pipe length The pipe length is generally 6 m, 9 m, 10 m, or 12 m. Other lengths can be determined by negotiation between the supplier and the buyer, and there should be no negative deviation in pipe length. 7.3.2 Pipe specifications and dimensions The pipe specifications and dimensions are shown in Table 4. 7.4 Physical and mechanical properties The physical and mechanical properties of the pipe should meet the requirements of Table 5. 7.
