Abstract

This utility model discloses a large-diameter plastic-reinforced water supply and drainage pipe, comprising: a corrosion-resistant layer, an insulation layer fixedly connected to the inner surface of the corrosion-resistant layer, a connecting reinforcing spiral column disposed inside the insulation layer, and a water-receiving layer fixedly connected to the inner surface of the insulation layer. The corrosion-resistant layer, made of chlorinated polyvinyl chloride, effectively resists external corrosion, significantly extending the pipe's service life. The insulation layer, made of polyethylene, has excellent insulation performance, effectively reducing heat loss and energy consumption, making it particularly suitable for transporting hot water or applications requiring temperature maintenance. The sound-absorbing arc-shaped column effectively reduces water flow noise by changing the water flow direction, improving the pipe's quietness. The water-receiving layer, made of cross-linked polyethylene, ensures its pressure resistance and flexibility, adapting to complex pipe installation environments, and serves as the direct contact layer for water flow, ensuring smooth water transmission.
