PVC/HDPE Double wall corrugated pipe production line
  Double wall corrugated pipe production line is the latest research achievement in the plastic extrusion field.Pipe production by direct extrusion molding process,High productivity,Reliable Quality. PE double wall corrugated pipe because of its superior structural design of pipe wall,compared to other structures of Heterotypic pipe wall  ensures the lightest weight,that is, a significant cost reduction makes it competitive in the market a substantial increase,and because of connection to facilitate,Reliable,without the complexity of special pipe fittings,so at home has been widely applied, a large number of alternatives to the traditional concrete pipe and cast iron pipe.in our country,as people get more and more concentration on the enviromental problem and beried drainagethe construction of Outfall pipe network,PE double wall corrugated pipe has a huge market and developing prospects. 

(1).Double wall corrugated pipe production line brief introduction:
    
    1.The use of pe high-performance screw,The machine Barrel has been slotted.Both inside and outside the layer bellows, respectively, from the  two extruder machine independent to feed,Can be realized both within and outside the layer use different raw material to produce pipe,To ensure high efficiency extrusion;
    2.Water cooling,Combination of strong wind cooling and water cooling of the corrugated forming system,can ensure continuous production of high speed.Advanced programmable lubrication system can greatly reduce the wear and tear forming module,Greatly extend the use of life,and to ensure that the operation of precision,to ensure the quality of the stability of pipe;
    3.Advanced belling Function on line,do not need to down line belling,Can significantly reduce the investment,and improve production efficiency;
    4.Special structure of the composite extrusion die head,both inside and outside the layer thickness uniformity,Forming a stable,can achieve stepless adjustment of the wall thickness;
    5.After the special alloy precision casting molding corrugated forming module,has high precision and intensity and excellent heat dissipation effect;
    6.The advanced of rapid replacement systemcan greatly reduce the time to replacement of modules
    7.Production lines using PLC or Large-screen touch-screen control system or Germany BECKHOFF Industrial Computer bus control systemWINDOWS XP2O Operating systema high degree of automation equipped with a sophisticated alarm system.Large 15-inch color touch screen HMIOperation Simple
    8.have Long-range communication functionachieve rRemote fault diagnosis and rule out the possibility
