Underground Sewage PE Steel Belt Reinforced Corrugated Pipe 1. Product Structure: HDPE steel skeleton reinforced spiral double-wall corrugated pipe is a type of structural wall pipe made by combining high-density polyethylene resin with steel. The pipe wall structure consists of three layers: the inner layer is a continuously wound solid wall pipe cavity, the middle layer is an inverted "U" shaped spirally wrapped steel plate reinforcement, and the outer layer is a PE layer that is molded into one with the outer surface of the inner layer PE pipe cavity, matching the wave shape of the steel plate reinforcement. The cross-section of the pipe is not only "U" shaped but also significantly enhances its strength against external pressure. 2. Product Standards: The People's Republic of China Urban Construction Industry Standard CJ/T225-2011 "Spiral Corrugated Pipe with Steel Belt Reinforcement for Underground Drainage" 3. Three Common Connection Methods for Underground Sewage PE Steel Belt Reinforced Corrugated Pipe: 1. Hot Melt Extrusion Welding This method uses specialized hot air extrusion welding tools to first heat the connecting ends of the Lu's underground sewage PE steel belt reinforced corrugated pipe, then extrude molten polyethylene material to fuse the polyethylene at both ends of the connection seam into a single unit. This method melts the polyethylene material into a whole, creating a rigid connection. 2. Heat Shrink Tube (Belt) Connection This method uses a fiber-reinforced polyethylene heat shrink belt as the inner layer and a heat shrink tube as the outer layer. The inner surface of the heat shrink tube is coated with hot melt adhesive, which, after heating, adheres tightly to the adjacent pipe ends, forming a unified connection. 3. Electric Heat Melt Band Welding This method utilizes electric heating elements embedded in the contact surface of the connection that generate high temperatures when powered, creating a rigid connection. The electric heat melt band welding structure consists of a polyethylene electric melt band with embedded resistance wire on the inner wall, tightly adhered to the outer surface of the two connected ends (covering the seam by more than two centimeters), secured with heat-resistant tape; at the same time, the inner wall of the pipe ends at the joint is supported firmly with removable tools, and then powered by an electric heat melt welding machine. The resistance wire heats, melts, and expands to create pressure, causing the polyethylene on both sides of the interface to diffuse into each other. After shutting off the power and allowing it to cool and solidify, a reliable connection is formed. 4. Characteristics of Underground Sewage PE Steel Belt Reinforced Corrugated Pipe: 1. Excellent physical properties: Lu's underground sewage PE steel belt reinforced corrugated pipe has good rigidity and strength, with excellent hot melt connection performance, facilitating the installation of plastic pipes. 2. Corrosion resistant, long service life, no need for anti-corrosion treatment, does not promote the growth of algae or bacteria, with a service life of up to 50 years and recyclable. 3. Strong water flow capacity: Lu's underground sewage PE steel belt reinforced corrugated pipe has a high flow rate, with a smooth inner wall, providing a water flow capacity that is 40% higher than that of other pipes. 4. Simple and convenient construction: The pipe is lightweight, with easy and straightforward connections, significantly reducing construction difficulty and saving project costs. 5. Leak-proof, preventing environmental pollution: The water tightness of Lu's underground sewage PE steel belt reinforced corrugated pipe, due to the use of electric heat melt connections, ensures excellent integrity of the pipe, preventing leakage and sewage contamination. 5.
