Spiral wound pipe, large-diameter wound pipe, double-wall wound pipe, hollow wound pipe is a kind of high-density polyethylene (HDPE) as raw material, a kind of pipe formed by wound and welding, due to its unique molding process, can produce up to diameter 3 meters of pipe, which is difficult to complete with other production processes. High-density polyethylene (HDPE) not only guarantees the product molding process and product quality due to its excellent welding performance, but also provides a variety of reliable methods for construction connection, such as electric heating welding, heat shrinking connection, etc., at the same time, this It is also an important reason why leakage rarely occurs. It is precisely for this reason that this spiral wound pipe has unique environmental protection functions that other pipes do not have. This provides a very effective method for pollution prevention and control that people are currently concerned about. So What are the advantages and disadvan
