Brief introduction:

The raw matorial of the plastic corrugation pipe is HDPE, resisting corrosive, acid and alkali, preventing the prestressing muscle from boing eroded. Many prestressing structure suffor severe influence from environment, such as deice salt or brine. Metal pipe have not permanent anticorrosive capability, cannot rosist water lcakage, while plastic corrugation is capable to provide a barrier protection for prestressing muscle, prevent the injurant pollution from penetrating the pipe, therefore, good pordurable performance of prestressing structure is guaranteed.
At the same condition, the friction coefficient of preset hole for plastic corrugation pipe are distinctly smaller than that of metal pipe, reducing friction loss of prestressing in the course of tension. Generally, friclion coefficient of the plastic pipe is 0.14, while for metal pipe it is 0.25, the plastic pipe having high strength, bearing jam on and it's airproof performance and leakage resistance is superior to that of metal pipe, more suitable to vacuum grouting.Don't electric.Plastic corrugation pipe have fine fatigue resistance.
