The prestressed round plastic Spiral pipes is made of high-density polyethylene (HDPE) or polypropylene (PP) as a raw material and produced by one-step molding with advanced production technology. It has good sealing and no water leakage, high ring stiffness and low conflict coefficient. It has the advantages of aging resistance, electrical corrosion resistance, good flexibility, not easy to be broken by tamping rods, and the new connection method makes the construction connection more convenient, and solves all the disadvantages of traditional metal Spiral pipes. It is an ideal product to replace the original metal Spiral pipes.

Circular prestressed plastic Spiral pipes is a new type of hole-forming material. Compared with metal Spiral pipes, it has the following advantages:

1. The original material of prestressed plastic Spiral pipes is HDPE. Its corrosion resistance is far superior to metals, not afraid of acid and alkali corrosion, it does not corrode itself, and can effectively maintain prestressed tendons from corrosion. Many prestressed structures are subject to severe external influences, such as deicing salt or salt water. When the post-tensioned member collapses or fails due to the collapse of the waterproof layer, the leakage of micro-cracks and the drainage facilities, the prestressed tendons may be corroded. The prestressed plastic Spiral pipes can provide the prestressed ribs with a barrier maintenance effect that is much better than that of the metal Spiral pipes, which can avoid the pollution of harmful substances penetrating the pipeline, thereby ensuring that the post-tensioned prestressed structure has better durability ;

2. Under the same conditions, the conflict coefficient of the pre-stressed plastic wave tube reserved channel is significantly smaller than that of the metal corrugated tube reserved channel, which reduces the pre-stress conflict loss during tension. In general, PVC plastic Spiral pipes, the conflict coefficient of plastic Spiral pipes is 0.14, and the conflict coefficient of metal Spiral pipes is 0.25; the strength of prestressed plastic Spiral pipes is high, not afraid of stepping on, and it is not easy to be beaten and broken by round plastic corrugated The sealing function and anti-leakage function of the tube is higher than that of the metal Spiral pipes and plastic Spiral pipes, and it is more suitable for vacuum grouting;

3. The prestressed plastic Spiral pipes are non-conductive and can avoid stray current corrosion, and the metal is a good conductor of electricity;

4. The prestressed plastic Spiral pipes has a better work resistance function, which can greatly improve the fatigue resistance of components.

Prestressed round plastic Spiral pipes are mainly divided into two types: round and flat, and the dimensions of the two plastic Spiral pipes are different. Specifically, it can be processed and produced according to the drawings provided by the customer.If you want to know more about it please do not hesitate to contact me. WhatsApp:+86-15966835076
