Polyethylene anti-corrosion adhesive tapes may have performance degradation and aging after a long period of use. At this time, we need to replace the adhesive tape. Today, manufacturers teach you how to remove the old polyethylene anti-corrosion adhesive tape:

1. You can use a blade to cut two parallel slits on the pipe that needs to remove the anti-corrosion layer, cut it in the axial direction, heat it at the corresponding position inside the pipe, and then open the slit with the chisel. Remove the anti-corrosion layer.
 2, can be removed according to the direction of the weld of the wrapped polyethylene anti-corrosion adhesive tape, which can reduce the difficulty of removing the old anti-corrosion adhesive tape.

3. It can also be removed by the heating device of the polyethylene anti-corrosion adhesive tape removing machine. After the heating device is close to the surface of the pipe, numerous eddy currents are generated for heating, and the surface of the anti-corrosion layer will become soft, and the pipeline anti-corrosion layer can be removed.
