Double Wall Corrugator Machine

We are offering double wall corrugator machine.
To strengthen corrugated pipe lor use in high pressure & high impact applications, volcano have developed a mile stone double wall corrugator of marvelously crafted article of plastic technology.
For similar material of inner & outer tube, single extruder is used with special die head, while for non-similar material of inner & outer tube, duel extruders with specific cross die head is used.
Here inner tube protects & conveys material at minimum loss of friction & pressure, while outer corrugation adds protective mechanical properties.
Depending on material, welding junction zone of adjacent pipe surfaces gives additional strength like as of spiral-breaded design.
