Scope

Main technical content: 5.1 Raw material requirements: The materials used for high-strength polyvinyl chloride (GHFB) cable protection conduits are modified polyvinyl chloride resins, which are extruded into pipes that meet the requirements of this standard for new composite reinforced pipes. The modified materials must not contain plasticizers, and the content of fillers shall not exceed 5%. 5.2 Product requirements 5.2.1 Color, appearance, and dimensions 5.2.1.1 Color: The color of the pipes is generally orange. Other colors shall be determined through consultation between the supplier and the buyer, and the color should be uniform and consistent. 5.2.1.2 Appearance: The inner and outer surfaces of high-strength polyvinyl chloride (GHFB) cable protection solid-wall pipes should be smooth, without obvious scratches, indentations, impurities, decomposition discoloration lines, or color unevenness. High-strength polyvinyl chloride (GHFB) has a resistivity of ≥11011 ohms and a static friction coefficient of ≤0.35. Connection sealing (water pressure of 0.010 MPa at 20°C for 30 minutes): No leakage.
