6. The line adopts advanced Siemens PLC control system and largeliquid crystal screen handling system, which realizes high automation,reliable operation and easy handling.

Double-wall corrugated pipe is new-type plastic tubing with theannular ripple on the outside wall and the smooth structure on the innerwall. Owing to many excellent features such as smooth inside-wall, highstrength, lower weight, corrosion resistant, long life, flexibility,easy connection and so on, it turns out to be a good product to takeplace traditional pipe and is widely used in city rainwater and sewagedischarge, drainage of residential district and mining enterprise, lowpressure water input of tap water and water l service, city planning,water arrangement etc.

HDPE large dia. Double-wall corrugated pipe has been designed anddeveloped carefully in our factory on the basis of the experience ofproducing tubing equipment many years and the most advanced technologyand manufacturing engineering in the world and it is a specialprocessing equipment at national leading level. It has adopted theman-machine interface to control on the whole line with high degree ofautomation, easy to operation and running steadily.

HDPE double-wall corrugated pipe line configured withhigh-efficiency single screw extruder, dual passage spiral compositeextrusion die, corrugated forming system, spray cooling water tank,hauling unit and stack unit.
