Handheld heating device for stripping corrosion-resistant layer of oil-gas pipeline

Abstract

The invention provides a handheld heating device for stripping a corrosion-resistant layer of an oil-gas pipeline. The device is mainly used for stripping the corrosion-resistant layer from the surface of the pipeline. The device mainly comprises an induction heating coil, an sb variable-frequency power supply, a temperature measurement probe, a flexible shell, a temperature control device, a heat insulation material and an operation handle. The induction heating coil is installed on the heat insulation material and then is connected with the sb variable-frequency power supply after being arranged in the flexible shell in an embedded mode. The temperature measurement probe is connected with the temperature control device and supplies control signals to the sb variable-frequency power supply. The operation handle is installed on the surface of the flexible shell. The power frequency electricity outputs the intermediate frequency electricity to the induction heating coil through the sb variable-frequency power supply to form a vortex on the surface of the pipeline, so that the corrosion-resistant layer with the softened surface is stripped after rapid heating treatment is achieved. The temperature control device controls the output of the sb variable-frequency power supply. The heat insulation material plays a role in heat insulating on the induction heating coil. The operation handle facilitates the movement of the heating device. The handheld heating device has the characteristics of being reasonable in structure, safe, reliable, convenient to use, free of pollution to the environment and free of external temperature interference.

Description

technical field [0001] The invention relates to a hand-held heating device for peeling off the anticorrosion layer of oil and gas pipelines, and relates to the technical field of peeling off the anticorrosion layer in the process of construction, maintenance and rush repair of oil and gas pipelines. Background technique [0002] In the process of construction, maintenance and emergency repair of existing oil and gas pipelines, the main method is to peel off the anti-corrosion layer on the surface of the pipeline by burning and grinding. This method has the following disadvantages: 1. Slow heating rate; 2. Low safety factor; 3. Low work efficiency and other problems; 4. Pollution of the on-site construction environment. There is a need for further improvement in these. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a hand-held heating device capable of rapidly heating the...
