Cluster tube
1. each inner pipe of the bundle pipe stands firmly on the inner wall of the outer pipe during the production process. The inner pipe of the pipe is smooth and convenient for construction.
2. the inner pipe of the pipe is subject to strict pressure test in advance, and then used to produce a complete cluster pipe. In addition, the special spiral shape of the outer pipe enhances the compression resistance of the traditional PE straight pipe, so the compression resistance of the pipe is very strong. 3. the pipe has strong acid and alkali resistance, so it can resist corrosion during the laying of seawater or wetland, so as to protect the communication line.
