TL - PVC electrical threading pipe a second production line belongs to the efficient production of the special equipment of high quality hard pipe. By the conical twin-screw extruder, vacuum sizing system, double traction and synchronous cutting mechanism. Some institutions can control independently, and can realize the function of the overall coordination, effective guarantee the quality of the plastic pipe material, at the same time with high efficiency, low energy consumption, the advantages of stable performance. Scope of application: this unit is suitable for the production of high quality hard UPVC pipe products, suitable for flame retardant PVC pipe, such as to drain hard products of the production. Double J/SGG PVC pipe production line is a new type of pipe production line in our factory launched. It combines advanced, reliability and practicability, especially suitable for the production of high quality PVC pipe. Its structural characteristics: two tube with crowded, control respectively. A tube failure, another tube to continue production. Suitable diameter: Φ 16 - Φ 50 mm. Stainless steel anticorrosion design, sealed performance is reliable. The whole pipeline design rationalization. The vacuum automatic control device. Two sets of independent control of auxiliary equipment can be produced at the same time on the double pipeline for pipes with different levels of pressure.
