How to choose a high-resistance reinforced double wall corrugated pipe? It's very special for this product. If we add the word “enhanced”, how do we understand this product?

Double wall corrugated pipes are advanced pipes imported from foreign countries. We have all seen the traditional concrete pipes. Not only are they heavy in quality, but they are also poor in impact resistance. Because the problems caused by the heavy are also a lot, the construction difficulty increases, and extra attention is needed when laying the pipe. This new type of double wall corrugated pipe drainage pipe is manufactured using polyethylene as a raw material. Polyethylene is a polymer plastic with strong corrosion resistance and abrasion resistance, and strong oxidation resistance. Pipes are generally 6 meters in length and can be lifted by one person. This is an unmatched advantage of traditional concrete pipes. Some people ask it’s so light, how about the stiffness? Its ring stiffness grades can reach SN4 and SN8.
So what is a high-resistance reinforced double-wall corrugated pipe? After the introduction of this kind of pipeline in China, after the independent improvement and innovation, a new steel pipe was added, which is referred to as steel belt corrugated pipe. Simply put, it is wound with molten polyethylene on the surface of the steel strip. It is an enhanced double-wall corrugated pipe.
How to choose a high-resistance reinforced double-wall corrugated pipe? I believe everyone knows that if there is a strong load on the buried surface, a steel strip pipe with a higher ring stiffness can be selected for laying. Today ’s problems will be introduced here first, and other problems, we can talk later accordingly.
