The full name of threading pipe is "insulating electrical sleeve for building". Generally speaking, it is a kind of white hard PVC pipe, anti-corrosion, anti-leakage and wire threading pipe. In the process of pipe making, adding some auxiliary agents will make PVC pipe with insulation, flame retardant, acid and alkali resistance, wear resistance. These characteristics make PVC threading pipe occupy a large market. After the PVC pipe leaves on the flame, the natural fire spreads along the pipeline. At the same time, because of its poor heat transfer performance, it can effectively protect the line for a long time in the case of fire, ensure the operation of the electrical control system and facilitate the evacuation of personnel.
The PVC pipe extrusion production line is used to produce PVC pipes. The pipes produced are mainly suitable for electrical threading, etc. The diameter of the production pipes ranges from 16-50 mm. Intelligent extrusion, high production efficiency, easy to use, forming stability. The main machine adopts conical twin screw extruder to improve mixing effect and high extrusion pressure. Using vacuum sizing technology, spray cooling, to ensure the quality of pipe.
