Scope

Scope: This standard specifies the definitions, symbols, and abbreviations of nano-modified high-density polyethylene (MUHDPE) alloy drainage pipes, product structure and connections, technical requirements, test methods, inspection rules, marking, transportation, and storage. This standard applies to nano-modified high-density polyethylene (MUHDPE) alloy drainage pipes. This product is mainly used in municipal engineering, transportation facilities, agriculture, and water conservancy construction, etc. Main technical content: 5. Technical requirements 5.1 Color: The colors of the inner and outer layers of the pipe material shall be uniform and consistent. The color is generally green, which can be agreed upon by both the supplier and the buyer. 5.2 Appearance: The inner and outer walls of the nano-modified high-density polyethylene (MUHDPE) alloy drainage pipes shall be smooth and flat, without air bubbles, cracks, obvious scratches, concavities, or decomposition discoloration lines. Ventilation grooves are not allowed. The end face of the sleeve shall be cut flat and perpendicular to the axis. 5.3 Length: The length of the nano-modified high-density polyethylene (MUHDPE) alloy drainage pipes is generally 6m, which can also be agreed upon by both the supplier and the buyer. The length of the sleeve shall include the part of the socket. The length tolerance is ±0.5% of the length. 5.4 Dimensions: The dimensions of the pipe materials shall comply with Table 1, and the minimum average inner diameter of the socket shall not be less than the maximum average outer diameter of the pipe.
