Qingdao day letter Thai Plastic Machinery Co., Ltd. specializes in producing plastic bellows equipment. Features: Wall cross-section of a double layer structure PE bellows, its smooth inner walls and outer walls equidistant arrangement has a trapezoidal hollow pipe structure. Nominal diameter (DN) :. Unit KN Features unique structure, high strength, inner smooth, friction, circulation, light weight, easy handling and installation, quick construction; rubber ring socket connection method is reliable, easy to guarantee construction quality; flexible interface. Anti uneven settlement capability; good anti-leakage effect, can withstand a variety of aggressive chemical media; no scaling within the tube, the basic need clear, buried life of five years or more. Pvc double wall corrugated pipe production process is hard PVC as the main raw material, pvc double wall corrugated pipe respectively from the inner and outer extrusion, molding, smooth inner wall, an outer wall trapezoidal corrugated sandwiched between inner and outer walls of the hollow walls plastic pipe This unit mainly polyvinyl chloride or polyethylene as raw material, the production of large-caliber double wall corrugated pipes. The pipe because of the unique structure of double-wall corrugated pipe machinery, light weight, good impact resistance, high stiffness, corrosion resistance, cold and heat advantages, widely used in the power cable sheathing ground heat, city row (to) water, agricultural irrigation, underground water infiltration irrigation and construction in the area up and down. Molds and auxiliary machines: machine and head high precision MPP bellows, module interchangeability module cooling water-cooled and air-cooled two can achieve belling, to ensure that the performance of pipe forming the ring pole cutting machine with excellent cutting precision bellows mechanical, the whole production line using the man-machine interface control system, with high self-control function, the replacement of the extruder and related parts and components to produce large-diameter PVC pipe reinforced.
