2. Introduction In addition to general plastic pipe has good corrosion resistance, high insulation, inner wall smooth, small flow resistance and other characteristics, double wall corrugated pipe adopts special hollowness structure, and the pipe has excellent ring stiffness and good strength and toughness, and light weight, impact resistance, and not easily damaged and so on. Double wall corrugated pipe are widely used in many areas such as municipal projects, residential quarter’s underground rain water and sewage drainage and so on.
3. Features In order to meet the demand of plastic market, HUASU Company designed and developed this HDPE Double Wall Corrugated Pipe Extrusion Line SBG 400 by absorbing advanced technology from foreign countries plastic machinery industry. This HDPE Double Wall Corrugated Pipe Extrusion Line is the latest study achievement in the plastic extrusion area. The whole production line is suitable for the high speed extrusion of HDPE, LDPE, and PP material. The complete production line adopts directly extruding (two extruders co-extrusion) and forming technology, human-machine interface control system. It makes high automation degree, reliable quality and stable production become true. And this pipe production line wins our home and abroad customers’ good reputation.
4. Extruder High speed, high efficiency extrusion single screw extruder is specially designed for extrude PE material. Grooved barrel, equipped with the lower noise fan, high speed and hard gear reducer. The inner and outer layers of the corrugated pipe are independently fed material by two extruders. It can make the inner and outer layers produce different material and guarantee high efficiency extrusion
5. Die Head It has two channel structure, nitriding and polishing handling, special designed mouth molds, suitable for different material and different ring stiffness corrugated pipe production. The special molds structure assures the inner and outer layer wall thickness even and forming stability.
