Scope

Scope: This standard specifies the definition, symbols and abbreviations, product structure and connections, technical requirements, test methods, inspection rules, marking, transportation and storage of nano-modified high-density polyethylene (MUHDPE) alloy pipes. This standard applies to nano-modified high-density polyethylene (MUHDPE) alloy pipes. This product is mainly used in municipal engineering, transportation facilities, agriculture, water conservancy construction and other fields; Main technical contents: 5.1 Color: The colors of the inner and outer layers of the pipe should 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 pipe should be smooth and flat, without bubbles, cracks, obvious scratches, indentations, or discoloration lines. There should be no ventilation grooves. The end face of the sleeve should be cut flat and perpendicular to the axis. 5.3 Length: The length of the nano-modified high-density polyethylene (MUHDPE) alloy pipe is generally 6m, which can also be agreed upon by both the supplier and the buyer. The length of the sleeve should include the length of the socket. The length tolerance is ±0.5% of the length. 5.4 Dimensions: The dimensions of the pipe should meet the requirements of Table 1, and the minimum average inner diameter of the socket should not be less than the maximum average outer diameter of the pipe.
