Reinforced high-density polyethylene double wall corrugated pipes for underground use

　　Product Introduction
　　The modified reinforced high-density polyethylene double-wall corrugated pipe for buried use is first modified and granulated to make special materials, and then extruded by a fully automatic ultra-high-speed buried modified reinforced high-density polyethylene double-wall corrugated pipe production line , the special material uses high-density polyethylene resin as the main component, and adds appropriate amount of inorganic nanoparticles, ultra-high molecular weight copolymerization compatibilizer, special anti-aging additives, etc. As for the surface, only the flexural modulus means, the impact parts are good, and the performance of planting is superior. And finally endow the pipe with excellent comprehensive performance.
　　Reference standard
　　The implementation standard GB/T194721-2019 "Buried Polyethylene (PE) Structural Pipeline System Part 1: Polyethylene double-reflected corrugated pipe" is the national standard of the People's Republic of China.
　　Product use
　　Municipal engineering road drainage and sewage pipes, urban sewage treatment plant pipe network construction, urban management, expressway, bridge drainage engineering, sewage interception pipeline engineering, flood discharge engineering, culverts and other fields.
　　Product features
　　1. Excellent mechanical properties: the pipe is made of special modified high-density polyethylene material, and the bending modulus of the material is as high as 1250MPa or more. Due to the double-wall corrugated structure, the interaction between pipe and soil is good, which endows the pipe with good compressive strength, and the highest ring stiffness can reach more than 20KN/m.
　　2. As a flexible pipe, it has good initial performance and high degree of retention. Compared with hand-made pipes, it has good longitudinal bending performance and can adapt to changes in the geographical environment and construction conditions of the industry. It is not good for pipe foundations caused by weak foundations. The adaptability to uniform settlement and dislocation is very strong, and the shock resistance is good.
　　3. The inner wall is smooth and free from scaling.
　　4. It has excellent physical properties, that is, it maintains good rigidity and strength, and also has good non-resistance, deformation resistance, high shear strength and good wear resistance.
　　5. Long service life. Since the molecular structure has no polarity, it has good chemical stability. Generally, factors such as soil filling, acid and alkali in the secondary use environment will not cause corrosion damage to the pipeline. In the case of buried, the service life of the modified reinforced high-density polyethylene double-wall corrugated pipe for buried can reach more than 50 years.
　　6. Easy installation and fast construction. Due to the light weight, simple connection, and convenient transportation, the labor intensity and mechanical usage are greatly reduced, the construction period is shortened, and the cost is saved. In the case of tight schedules and poor conditions for travel workers. Its advantages are more obvious. The interface is well sealed and has the characteristics of zero full water.
　　7. The pipe meets the national environmental protection requirements, is non-polluting, non-toxic, and can be recycled repeatedly.
