2. Introduction Double wall corrugated pipe inner layer smooth, outer layer trapezoidal corrugated-size, hollow wall between inner layer and outer layer. The special design of pipe wall structure makes the pipes have many advantages such as: high ring stiffness, light weight, high pressure, good toughness, corrosion resistance, good wear resistance, construction convenient, low installation cost, long service life and so on. Double wall corrugated pipe is widely used in areas such as the transformation of municipal engineering, construction, industrial and agricultural drainage, agricultural water-saving irrigation and sewage treatment works and other fields. Double wall corrugated pipe is the best product instead of traditional cement pipe, cast iron pipe and other materials pipe.
3. Features In order to meet the demand of plastic market, HUASU Company designed and developed this HDPE Double Wall Corrugated Pipe Extrusion Line SBG800 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 extruding area. The whole extrusion line is suitable for the high speed extrusion of HDPE, LDPE, and PP material. The complete line adopts directly extrude (two extruders co-extruding) 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 extruding 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 extruding.
5. Die Head The extrusion die head has two channel structure, nitriding and polishing handling, special designed mouth molds, suitable for different material and different ring stiffness pipe production. The special molds structure assures the inner and outer layer wall thickness even and forming stability.
