The reinforced polyethylene spiral corrugated pipe has the advantages of convenient construction, good flexibility, high interface quality, corrosion resistance, anti-aging and wear resistance. The product diameter is DN200-2000mm, and the application range is wide. Compared with the PE double-wall corrugated pipe, the inner rib reinforced polyethylene (PE) spiral corrugated pipe changes the ordinary socket connection (or hot-melt shrinkage belt connection) to the electrofusion welded joint, that is, the socket of the inner rib tube and A resistance wire is respectively arranged on the socket, and the socket is completely fused by the heating action of the resistance wire. This interface not only achieves zero leakage at the pipe interface, but also completely integrates the entire pipe section, increasing the flexibility of the pipe and improving the safety and stability of the pipe.
Reinforced polyethylene PE spiral corrugated pipe is a newly-plasticized inner rib reinforced PE winding pipe newly developed on the market. The pipe is extruded with polyethylene or high density polyethylene resin as the base material to extrude polyethylene covered hose, and the outer half corrugated structural component The inner ribs are wound to form a tube having a flat inner surface and a spiral corrugation on the outer surface. There is an upright inner rib in the middle of the pipe corrugated, which improves the ring stiffness and enhances the stability of the wave peak, which is beneficial to the pressure resistance and impact resistance, and effectively saves the amount of plastic. The inner rib reinforced polyethylene (PE) spiral corrugated pipe has the outstanding features of large external surface area, strong joint pressure resistance, high ring rigidity and good welding effect, and allows the buried depth to exceed the ordinary polyethylene plastic pipe. It is mainly used for buried drainage pipelines for large-scale projects such as municipal, construction and power plants with medium temperature below 45 °C; old city reconstruction, rain and sewage diversion project, sewage treatment plant, garbage disposal plant drainage pipeline; seawater, industry, chemical industry Corrosive sewage pipelines in factories, pharmaceutical factories and other industries, as well as irrigation and drainage of farmland. Widely used in drainage engineering and users reflect well.
