Description of SBG500 UPVC Double Wall Corrugated Pipe Extrusion Line: Diameter scope: (OD) 160mm-500mm Double wall corrugated pipe line Features: UPVC Double Wall Corrugated Pipe Extrusion Line SBG500 developed by us absorb advanced technology from foreign countries plastic machinery industry. This UPVC 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 UPVC material. The complete line is adopted human-machine interface control system. It makes high automatical degree, stable production and great output become true. We adopt one efficiency conical twin screw extruder with high extrusion capacity in this line. There are special designed co-extrusion moulds made by alloy steel for making huge diameter UPVC corrugated pipe. Double spiral design with excelent quality alloy steel of the moulds can meet all of the production requirements. This plastic corrguated pipe machine is made of vibration sieve, high speed mixer machine and cooling machine, material feeder conical double screw plastic extruder,(single screw extruder) handpiece, double-wall accordion pipe shaper, plastic pipe-expanding machine, pilling bin, water chilling unit, air compressing machine. It can be used to produce PVC, PE plastic double-wall accordion pipe and plastic single-wall accordion pipes.
