Prestressed pipe production line can be used for bridge construction slope anchoring plastic bellows (round, flat) is a substitute for metal bellows. Through the painstaking research of our technicians, we have successfully solved the problem that the thickness of the pipeline cannot be cooled, which leads to slow production speed and high quality and high speed. Reduce the cost and improve the characteristics of prestressed bellows production line: plastic bellows can provide a much better barrier protection for prestressed tendons than metal bellows, prevent the pollution of harmful substances through the pipeline, post-prestressed structure has better durability; Under the same conditions, the friction coefficient of the plastic bellows reservation hole is obviously smaller than that of the metal bellows reservation hole, which reduces the friction loss of the prestress in the tension process.

Generally speaking, the friction coefficient of plastic bellows is 0.14, and that of metal bellows is 0.25;) Plastic bellows have high strength, are not afraid of pressure, and are not easy to be cut by vibration. Their sealing performance and leakage performance are higher than those of metal bellows, which are more suitable for vacuum grouting. Plastic bellows are non-conductive and prevent corrosion by dispersed current, metal is a good conductor of electricity;) Plastic bellows have better fatigue resistance and can greatly improve the fatigue resistance of components.

Several uses of prestressed pipe:

1. Residential use: residential use, cold and hot water and heating for villas.

2. Public buildings: water supply and floor radiant heating for office buildings, markets, theaters, military barracks and other public buildings.

3. Airport, passenger station, parking lot, garage, highway.

4. Animal and plant uses: zoo, botanical garden, greenhouse, chicken farm piping.

5. Sports facilities: swimming pool, sauna, hot and cold water pipes.
