PVC pipe manufacturing machines have advantages such as high automation, high production efficiency, and stable product quality. By adjusting parameters such as temperature, pressure, and speed of the extruder, PVC pipes of different specifications and uses can be produced to meet the needs of different fields. The extruded PVC pipe needs to be immediately cooled to prevent deformation. The cooling system usually includes a water tank or an air cooling device, which is used to quickly reduce the temperature of the pipes.
