PVCPipe production line is also called PVC construction pipe production line, PVC double pipe extrusion production line, electrical pipe production line, electrical pipe production line, SJSZ-51/106 cone type double pole extruder equipped with double tube mold head, double tube vacuum diameter water tank, double tube tractor, double tube fixed length cutting machine, double unloading frame composition, PVC pipe production line unique screw design, materials will not stay too long in the cylinder, mixed together for plasticizing effect very well, the used reducer box because it is a performance comparatively superior. PVC pipe production line look very nice, work up very stable, won't produce much noise, production line use the exhaust system for vacuum exhaust, can easily evaporate the material contained in the water out and exclude it from the body, the quality of the product has been greatly improved, one-mode double tube, production efficiency can also be at least twice improved, can achieve individual control, operate very convenient, the main motor of PVC pipe production line uses controllable DC regulator or frequency converter, has a very stable point torque output, can achieve stepless adjustment speed PVC pipe production line is produced directly from powder, no need granulation, save electricity and manpower, production efficiency is also very high. PVC wire pipe is according to the outer diameter of the tube marked, 16, 20, 25, 32, 40 is the outer diameter of the tube standard, conforming to the national standard JG 3050-1998, according to the wall thickness different, its inner diameter different, the wall thickness of the PVC wire pipe commonly used is a thickening type A, B general type, C thin wall type three. Pipe B ye kɔc juëc luɔ̈ɔ̈i në luɔɔi.
