Production line features: PVC prestressed plastic corrugated pipe equipment, mainly for the production of highways, overpasses, viaducts, railway bridges, concrete protection strand tension plastic bellows. Prestressed single bellows into the hole as a new material, as compared with metal bellows, it has not afraid of acid, alkali corrosion, sealing, no water seepage, leakage of plasma, ring stiffness, low coefficient of friction, anti-aging, anti- galvanic corrosion, soft toughness, not easy to be tamper demolition, construction and easy to connect, solve all the drawbacks of traditional metal bellows. Cui Plastic Machinery Manufacturing Co., Ltd. Qingdao in the digestion and absorption of imported equipment positive basis, relying on scientific research institutions, research and development and production of a single wall corrugated HDPE pipe prestressed pipe production line based. Production specifications from φ50mm-φ160mm. The project is to fill the gap. Full set of equipment from the extruder, extrusion dies, molding machines, cooling device, traction machine, sawing machine, reverse station components. The device is fully absorbed the advantages of similar foreign equipment, with a compact, flexible operation, a multi-purpose, high efficiency (up to 2500 m Nissan), energy saving features.
