The machine can be used to produce PE double wall corrugated pipe with the inner diameter of up to 500mm.

1. This corrugated pipe machine can realize highly efficient cooling of the mould blocks and the fast molding of double wall corrugated pipes through adopting Zhongyun's patent technology of PQF^TM powered quickly cooling technique so as to greatly raise the production efficiency of double wall corrugated pipes.

2. The calibrating mandrel on our double wall corrugated pipe machine has a super abrasion resistance, and the lifespan of our calibrating mandrel is as long as the whole machine, which means that you needn't to change the calibrating mandrel during your long-term use of the double wall corrugated pipe machine. Even using the recycled PE material for production of the double wall corrugated pipe, our calibrating mandrel will not be abraded.

3. The advanced programmable lubricating system decreases abrasion of mould blocks to a minimum while lengthening their lifespan and ensuring running precision of the corrugated pipe machine and stable quality of the corrugated pipe.

4. Compatibility of mould blocks between different corrugator models.
