Abstract
The utility model discloses a removing device of pipeline anticorrosive layers. The removing device of the pipeline anticorrosive layers is mainly used for removing the anticorrosive layers on the inner walls and the outer walls of pipelines such as a natural gas pipeline and a petroleum pipeline. The removing device of the pipeline anticorrosive layers comprises a ferrite, a variable-frequency power source and a coil. The coil is installed on the ferrite. The coil is connected with the variable-frequency power source. The variable-frequency power source supplies high-frequency voltage to the coil. After the coil is contacted with the outer wall of a pipeline, a magnetic field with low voltage and a large current is generated on the wall of the pipeline through the ferrite, the wall of the pipeline is rapidly heated, and therefore the anticorrosive layers are softened and can be conveniently removed. A temperature control device can also be additionally arranged. The temperature control device is connected with the variable-frequency power source. A temperature can be set by the temperature control device according to the requirement for removing the anticorrosive layers. The output of the variable-frequency power source is controlled. The removing device of the pipeline anticorrosive layers has the advantages of being reasonable in structure, controllable in temperature, high in removing efficiency and safe and reliable in operation.
