The second-hand three-layer PVC extrusion line is mainly used for producing PVC pipes of various diameters and wall thicknesses in agriculture, construction, cable laying, and other fields. The unit consists of a conical twin-screw extruder, two claw, three claw and other vacuum modes. You can choose between saw blade cutting or planetary cutting. According to customer requirements, an inner wall spiral coil manufacturer is attached. Production of inner wall spiral tube, inner wall hollow core foam tube, etc. The planetary cutting machine adopts fully automatic computer control, which has the advantages of simple operation and reliable performance. It has reached the world's advanced level.

Performance advantage: SJZ series conical twin-screw extruder can extrude more than 2 three-layer PVC pipes. The pipeline interlayer is made of high calcium polyvinyl chloride or polyvinyl chloride foam material.
1. The host adopts a super wear-resistant alloy screw cylinder, and the double screw feeder provides uniform feeding without bridging;
2. Optimization design of PVC three-layer PVC pipeline mold, highly polished channel chrome plating, wear-resistant and corrosion-resistant; Adopting dedicated sizing sleeves, with fast production speed and good pipe quality;
3. The cutting tool adopts a rotating clamping device to adapt to different pipe diameters, avoiding the trouble of frequent replacement of clamps. Equipped with a new adjustable floating chamfer mechanism, the chamfer size can be adjusted according to the pipe diameter and wall thickness, allowing for one-step cutting and chamfering. Closed vacuum device for better chip suction effect.
2. Applications
The second hand three-layer PVC extrusion line is a three-layer co extruded composite drainage pipe, with both inner and outer walls made of hard PVC to ensure that the pipeline has sufficient strength and other physical properties. The middle layer is made of PVC with a special formula, with a relative density of 0.7-0.9g/cm3. The structure of the layer is micro closed pores. This special structure cleverly applies the principle of Type I structure in material mechanics. It can be observed that the intermediate layer is a soft colloid, which not only has all the advantages of PVC (hollow wall) pipes, but also has the advantages of sound insulation, heat insulation, shock resistance, impact resistance, light weight, and low price compared to solid wall pipes.
1. Lightweight (density 0.9-1.2g/cm3) and affordable.
2. Smooth inner wall, low friction coefficient, and improved fluid transport efficiency
3. The impact strength is high, and the ring steel is twice that of ordinary PVC-U
4. It has good weather resistance and can be used at -30 ℃ -70 ℃. It has good dimensional stability when temperature changes occur
5. The special composite multi-layer structure greatly improves the sound insulation performance of the pipeline
6. Strong self ignition and self extinguishing performance
7. Excellent corrosion resistance
8. The service life of pipelines has increased by 4-7 times compared to ordinary pipelines
The installation cost of composite drainage pipes is lower than that of ordinary pipes. After comprehensive comparison of many factors such as corrosion resistance, wear resistance, and weather resistance, the performance of composite drainage pipes is higher than that of ordinary polyethylene pipes.
