To strengthen corrugated pipe for 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 extruders 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 corrugated outer adds protective mechanical properties Depending on material, welding junction zone of adjacent pipe surfaces gives additional strength like as of spiral breaded design.

This pipe made from a wide range of thermoplastic materials including PE, HDPE & PP etc. These pipes are used in various indoor, outdoor, underground applications like.

• Agriculture: Land drainage systems, irrigation, Greenhouse drainage, field irrigation etc.

• Automotive: Air conditioning ducts, radiators, vacuum lines, gas lines.

• Construction: Sewage & Drainage foundation drainage, cable ducts, heating & ventilation ducts, water pipe insulation, Vacuum Hoses.
