Prestressed corrugated pipes, concrete prestressed plastic corrugated pipes are the lowest in the country
For a long time, most prestressed projects have used metal corrugated pipes as components. hole material, but metal bellows have poor sealing performance, are easily damaged, easy to rust, and have high friction. In order to overcome these shortcomings of metal bellows, and also to provide an additional anti-corrosion guarantee for prestressed tendons, the raw material is (high-density polyethylene ) plastic corrugated pipes are used as a revolutionary product of bonded post-tensioning to increase the life of prestressed concrete structures.
The physical and mechanical properties of plastic corrugated pipes are listed in the following table:
Serial number project technical indicators
Ring stiffness
The irrecoverable residual deformation under the specified load of lateral load does not exceed the pipe diameter
If the cross-sectional deformation does not exceed the diameter under the specified bending radius and number of times for flexibility, use a plug gauge to test
Under the specified internal or external pressure for sealing, the pipe wall and joints will not break or leak
Wear resistance Residual wall thickness after tension wear under specified damage test conditions
Bonding performance b(bb,)
