Specification: 50-200mm Application: This production line is mainly used to produce PE spiral pipes which are widely used as protecting sleeves of optic or electric cable, and they are increasingly used in fields of electricity, telecom, post activities, constructions of express way and port. These pipes are characterized by high intensity and tenancy, erosion resistance, constant shape and easy transportation and execution. They can be processed and bent into long pipes with various radians. Owing to these advantages, they are very popular with clients engaged in many fields. We are the most professional manufacturer in China for this kind of pipe machines, we design and develop the corrugated pipe mould block, which is the most important part in forming. Every year, we will sell many lines to abroad and home market, our old customers will buy dozens of lines from us. Features: 1. The production line produces all kind of polyolefin material, multi-layers spiral strengthening pipe. 2. The screw extruder especially used for polyolefin material possesses effective plasticizing effect and high extrusion speed. 3. The special detached type compounding screw and die head with structure and reasonable channel are applicable to produce pipes with smooth inside and outside face. 4. Unique calibration and cooling mode is capable of producing pipe with diameter from Φ50 to Φ200mm, production speed is up to 0.4-1.5m/min. 5. Optimum spiral copper sizing sleeve, its entrance carrying pre-cooling and powerful vacuum device to suit for high speed extruding pipe. 6. Stainless steel cooling tank is tree-dimensional regulation, longitudinal moved motor. 7. High efficient cooling comes from peculiar spraying nozzles and high efficiency water pump.
