Plastic Spiral Prestressed Corrugated Pipe Extrusion Machine

Prestressed plastic corrugated pipe is made of HDPE, which is mainly used in post tensioned prestressed cement structure and hole forming of tie rod. It has the advantages of good sealing, no water and slurry leakage, high ring stiffness, small friction parameters, aging resistance, electric erosion resistance, good flexibility and elasticity, not easy to be chiseled by tamping rod and new connection mode, which makes construction connection more convenient. It is mainly used in highway and railway, Bridges, slopes, high-rise buildings and other long-span tensioning projects are under construction.
