Sell PE/PP/PVC double-wall corrugated pipe extrusion line

KR-series PE/PP/PVC¢*-¢**0 horizontal or vertical double-wall corrugated pipe extrusion line is totally developed by our company, which is one of the projects under national Torch Plan with the itemed no. ***1EB*****7 and file no. ***1.**0 issued by State Science and Technology Department. The project fills the blank of the technology in the field locally. Double-wall corrugated pipe has advantages of light weight, easy installation, low cost, chemically corruption-resistant, dirt-free on the inside wall, impact resistance, high temperature resistance, high capability of quick transferring for cracks, good conductivity for electricity, etc. The steel frame winding hollow corrugated pipe can be produced when related auxiliary equipped after slightly revising the PE double-wall corrugated pipe extrusion line. Main uses: drainage in cities, dirt discharging project, sewage, irrigation, sand prevention, low-pressure water supply, revamping of dirt discharging duct, cabling protection, etc
