**Steel-Belted Sewage Pipe - Sewage Pipe Manufacturer** In this rapidly developing economic environment, enterprises must survive by quality, seek development through integrity, and expand through service. It is increasingly difficult to close deals solely based on low prices; more and more people care about cost-effectiveness and quality, as quality is fundamental. Luoyang Guorun New Materials always adheres to the principle of understanding customers' needs and concerns, repaying customers with product quality and a perfect after-sales system. **Steel-Belted Sewage Pipe - Sewage Pipe Manufacturer Definition:** PE and steel belt are fused together to form a composite structure wall pipe. The structure comprises three layers: high-density polyethylene as the matrix, and the spirally wound high-strength steel belt as the reinforcement. Using new technology, the steel belt is fused with polyethylene, providing the flexibility of plastic pipes and the rigidity of metal. **Characteristics:** Large diameter, high strength, 300-3000mm, with ring stiffness above 12.5KN/M, lighter than concrete pipes and other pipes, and with superior performance. **Corrugated Pipe Characteristics:** 1. Good pressure resistance and impact resistance. 2. Good economy. 3. Good chemical resistance. 4. Good aging resistance. 5. Excellent drainage flow performance. **Connection Methods:** 1. Hot melt extrusion welding 2. Electric thermal fusion belt connection 3. Heat shrink tubing connection 4. Clamp connection **Specifications:** DN300-3000mm **Main Characteristics of Steel-Belted Sewage Pipe - Sewage Pipe Manufacturer:** 1) High Ring Stiffness For ordinary buried drainage plastic wall spirally wound pipes, achieving a ring stiffness above SN 8 is difficult. However, the new structural pipes can easily reach SN8, SN12.5, and even SN16, or higher. On the other hand, the steel-plastic composite pipe, with a steel pipe as the middle layer and polyethylene on the inside and outside, has excellent anti-corrosion properties. Therefore, this composite anti-corrosion pipe can be used in various harsh environments. For example, in some coastal areas, due to corrosive substances in the soil, the lifespan of concrete pipes is short, and there is a need for corrosion-resistant buried drainage pipes. In the past, the lack of products with high ring stiffness could not meet design requirements, but now metal-reinforced spirally wound structure wall pipes can be used. 2) Material Cost Savings In addition to these performance improvements, another significant advantage is material cost savings. Compared with other plastic pipes of the same diameter and ring stiffness, steel-belt reinforced polyethylene (PE) spiral corrugated pipes can save nearly half of the material consumption, with polyethylene accounting for only 2/3 of the composite pipe's overall weight. In the context of rising plastic prices, this is a very good solution for reducing material costs. The ring stiffness achieved by thin steel belts shaped into ribs far exceeds the effect produced by a very thick polyethylene structural layer. By appropriately designing the thickness and height of the steel ribs, the required ring stiffness can be easily achieved. In metal-reinforced spirally wound structure wall pipes, the role of polyethylene is to provide corrosion resistance and wear resistance, so the material used for the steel ribs is minimal, and the amount of polyethylene is also kept low. 3) Combination of Steel and Plastic The key to the success of metal reinforcement is to ensure a strong bond between steel and plastic. This requires the steel to be firmly bonded to the plastic, with no separation allowed between any two layers. To achieve optimal bonding performance, we have conducted extensive research and testing during the development of the pipes. The current process involves pre-coating the steel belt with a special resin as the intermediate layer between steel and plastic. Additionally, the process temperature, pressure, and cooling time must be strictly controlled, ensuring that each layer of steel and plastic is perfectly fused at the appropriate temperature. Another key point for achieving metal reinforcement is to adequately protect the easily corroded metal layer. In the structural design of the pipe, the steel ribs are completely covered by inner and outer polyethylene. The inner and outer surfaces that come into contact with the transported liquid, surrounding soil, and groundwater have a certain thickness of polyethylene layer, ensuring the corrosion resistance and wear resistance of the metal-reinforced spirally wound structure wall pipe. **Applications of HDPE Steel-Belted Corrugated Pipe: Steel-Belted Sewage Pipe - Sewage Pipe Manufacturer** Suitable for various drainage and sewage systems used in municipal, industrial, agricultural, and transportation engineering construction. Utilizing multiple patented technologies of our company for plastic-steel forming and composite technology, the pipe materials are reliably compounded, enhancing their performance and increasing their ring stiffness (above SN10). The elastic modulus of steel is nearly 200 times that of polyethylene (with the elastic modulus of carbon steel around 190,000 MPa). The combination of the advantages of metal and plastic is clearly an ideal way to achieve high rigidity with low consumption, organically combining the high rigidity and high strength of steel with the excellent properties of plastic, such as corrosion resistance, wear resistance, and flexibility, thus leveraging the advantages of both while compensating for their disadvantages, achieving the unity of high performance and low cost. **Luoyang Guorun New Materials -- We look forward to your participation!** Technical Guidance: Manager Sun, 136 9888 7149, 0379-65227507 Factory Location: China, Luoyang Airport Industrial Cluster, Zhejiang Business Industrial Park.
