Advantages of COD pipeAdvantages of COD pipe: 1. Each inner pipe of COD pipe stands tightly on the inner wall of the outer pipe during the production process. 2. The inner tube of the COD pipe is smooth and the construction is convenient. 3. The inner tube of the COD pipe is subjected to rigorous compression test in advance, and then used to produce a complete COD tube, together with the special spiral shape of the outer tube, which further enhances the compression resistance of the traditional PE straight pipe. Therefore, the pressure resistance of the COD tube is extremely strong. Even if an earthquake occurs and the building collapses, safety can be guaranteed. 4. COD pipes are extremely resistant to strong acids and alkalis, so they are resistant to corrosion during the laying of seawater or wetlands. Therefore, the purpose of protecting the communication line can be achieved. 5. The production length of COD pipes can reach more than 1000 meters per roll, therefore, the efficiency of laying communication lines can be improved.
