The double wall corrugated pipe can be formed directly by extrusion working process, it has the features of stable quality and high efficiency. Compared with other kinds of profile pipes, double wall corrugated pipe designed reasonably, its low weight reach the lower production cost and imporve the market competition. Because of convenience in making connections, stability and reliability and accessories sample,the double wall corrugated pipe is widely used in various aspects,and thus replace the traditional concrete pipe and cast iron pipe.
1.The extruder adopts high efficiency screw specially used for polyolefin, it has the features of stable quality and high efficiency. It adopts two sets of extruders, which can be feeded with vary materials with different colors.
2.co-extrusion die head with specially helical structure to make the wall thickness even smooth and stable production.
3.The forming machine adopts automatic power-off protection deivce.The forming machine can automatically exit from the die head to avoid equipment failure in the case of electricity failure suddenly. Equipped with new type high transmitting ratio reducer,
4.The corrugated forming system is in combination with water cooling and air cooling to ensure high production speed continuously. Advanced programmable lubricating system minimizes the wear so as to increase the life of service and ensure work smoothly with high precision to ensure the products quality stability.
5.Mould adopts special aluminum alloy material and high precision die casting forming mould method, it has the advantages of high precision,high strength,good wearability and better heat dissipation.
6.Wave structure launched a comprehensive new optimization design to reach the best combination of high-rigidity and low weigth.
