DN700-2200mm Extrusion machines of thermoplastic Spiral Wound Chemical Storage Tanks

The machine is designed for the manufacture of large diameter HDPE or PP/PPH spirally wound pipes on a steel mandrel, without gas preheating, produced by one or more high-speed extruders.This line is Simens PLC computer controlled . Production efficiency is 5-8 times higher compared the traditional way of sheet bending and welding. The tank is flat and beautiful, and the top of the tank is thin and the bottom is thick,the machine can be upgraded to produce a special double wall for leakage control.
