Corrugated plastic pipe, also known as prestressed concrete plastic bellows. It is made of high density polyethylene mechanically extruded shape for the shape of the corrugated plastic pipe. It has the versatility, interchangeability, supporting reasonable, easy to use features. Widely used in roads and bridges, railway bridges, buildings, water, electricity and other key national major projects conduit (cable jacket). Species by the shape of the plastic pipe is divided into: corrugated plastic pipe and plastic corrugated flat tube. Plastic corrugated pipe inner diameter is 40-130mm; corrugated plastic tube flat width of 19-25mm; length 46,55,60,72,90mm. Press the outer style is divided into: double wall corrugated pipe and single wall corrugated pipe extruder generally equidistant ranging from deep PVC corrugated pipe equipment, graded screw (see soft poly ethylene effective catch extruder). Corrugating device consists of mold, transmission and control system. Wherein the mold is composed of dozens of top and bottom off the continuous blow molding composition bellows equipment prices, upper and lower dies are fixed to the crawler belt drive in two. When the transmission is driven by rotation of the mold, the upper and lower molds repeated closing - opening operation. Constitute a closed mold cavity forming a circular tube, blow molded bellows after the mold is opened, make the products ejection. Corrugating apparatus products also play a role in shaping and traction.
