Plastic corrugated pipe Hengshui prestressed plastic corrugated pipe manufacturer national standard plastic corrugated pipe
As a hole-forming material for prestressed post-tensioning method, corrugated pipe is an important part of the prestressed system. For a long time, metal corrugated pipe has been used as a component in prestressed projects. Hole material, in order to overcome the shortcomings of metal bellows with poor sealing, easy damage, corrosion and high friction, and also to provide an additional anti-corrosion barrier for the prestressed tendons, it is recommended to use plastic bellows made of polyethylene or polypropylene as the bonded material. A revolutionary product of post-tensioning to increase the life of your structure.
Performance indicators of plastic corrugated pipes
The prestressed hole forming system composed of plastic corrugated pipes and accessories should meet the needs of post-tensioned prestressed grouting. In addition to heat welding connections between pipes, special The entire hole-forming system of the sealed connection device is equipped with exhaust, drainage and grout pipes, which can meet the needs of pressure grouting or vacuum-assisted grouting.
Plastic corrugated pipes, material properties comply with / regulations.
Plastic corrugated pipes are generally black, and defects such as melt rupture, hard lumps, serious bubbles and other defects are not allowed on the inner and outer walls. In order to achieve a smaller friction coefficient and ring stiffness, plastic bellows should be a pipe with annular corrugated intervals.
The plastic corrugated pipe is equipped with a sealing device that can reliably connect to the prestressed anchor.
The inner cross-sectional area of the plastic corrugated pipe is at least twice that of the prestressed tendon.
The friction coefficient of plastic corrugated pipes is , minimum bending radius.
