In addition to general plastic pipe has good corrosion resistance, high insulation, inner wall smooth, small flow resistance and other characteristics, double wall corrugated pipe (IDΦ90mm-Φ250mm) adopts special hollowness structure, and the pipe has excellent ring stiffness and good strength and toughness, and light weight, impact resistance, and not easily damaged and so on. Double wall corrugated pipe are widely used in many areas such as municipal projects, residential quarter's underground rain water and sewage drainage and so on.

Double wall corrugated pipe line features:

 Extruder: High speed, high efficiency extrusion single screw extruder is specially designed for extrude PE material. Grooved barrel, equipped with the lower noise fan, high speed and hard gear reducer. The inner and outer layers of the corrugated pipe are independently fed material by two extruders. It can make the inner and outer layers produce different material and guarantee high efficiency extrusion

Die head: it has two channel structure, nitriding and polishing handling, special designed mouth molds, suitable for different material and different ring stiffness corrugated pipe production. The special molds structure assures the inner and outer layer wall thickness even and forming stability.

Corrugator: Corrugator is adopted horizontal structure with chain type transmission, equipped with open water cooling system and vacuum forming system. It greatly increases the production speed. The belling on line function decreases investment cost and improves production efficiency. Mold moving adopts synchronous upper and lower mechanical drive system and advanced self-lubrication system. It assures moving accuracy and corrugated pipe quality stability.

Mold blocks: Double Wall Corrugated Pipe forming molds which are formed by special aluminum alloy material through precision casting. They have high precision and strength, and excellent heat dissipation.

Cutting machine: High-strength alloy steel blade, Rotary cutting, smooth pipe incision, dustless cutting. The tracking device makes the cutting location precision. Germany Siemens professional PLC programmed controlling system makes operation easy and sensitive.

Control system: it adopts Siemens professional PLC control system, 15 "large color touch screen human-machine interface, high automation, reliable running, easy operation, remote communication function which can realize remote fault diagnosis and rule out the possibility.
