Description
Technical field
The present invention relates to pipe-line maintenance damage repair technology field, be specifically related to a kind of method for cleaning being exclusively used in oil and gas pipes 3PE anticorrosive coat and cleaning equipment.
Background technology
Existing oil and gas pipes 3PE anticorrosive coat, mainly based on polyethylene and high density polyethylene (HDPE), 3PE anticorrosion is typically made up of 3-tier architecture: ground floor FBE, second layer adhesive layer, third layer polyethylene layer, three kinds of material mixing are combined together, is allowed to form excellent anticorrosive coat with steel pipe strong bonded through processing.
But during dimension first-aid repair construction, anticorrosive coat is removed becomes the difficult problem hindering repairing, and the mode currently mainly taked has three kinds, the first is first to remove with scoop with after baking again, is often repeated several times and just can remove, and efficiency is low and has naked light, dangerous, to environment；The second is to use mechanically or manually mode to carry out scraping, pipe surface often causes mechanical damage, and may produce spark；The third is to utilize Electromagnetic Heating or infrared heating technique to heat pipeline, again by the way manually cleared up one by one after making anticorrosive coat soften, remove anticorrosive coat, this technology consuming electric power is big, efficiency is low, operation complexity, can destroy pipeline body metallic crystalline structure to a certain extent owing to temperature (about 300 degree) is high, affect tube performance.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of method for cleaning being exclusively used in oil and gas pipes 3PE anticorrosive coat and cleaning equipment, it solve these above-mentioned problems.
The technical solution adopted in the present invention is as follows:
A kind of cleaning equipment being exclusively used in oil and gas pipes 3PE anticorrosive coat, including power supply box, described power supply box connects control chamber by electric wire, motor is set in described control chamber, the outfan of described motor connects drive system, described drive system connects roller, and described roller front portion is provided with baffle plate, and the left and right sides, described baffle plate lower end is both provided with 3PE anticorrosive coat cutting knife；Described roller bottom is provided with electromagnetic radiation plate, described roller is provided with some spines, is provided with controller outside described control chamber.
Preferably, described electromagnetic radiation plate bottom is provided with rectangular waveguide.
Preferably, described spine is high duty metal manufacture.
Preferably, the frequency of described electromagnetic radiation plate 50 hertz, rated voltage 220-380V, voltage adaptation scope positive and negative 20%, rated power 4-40KW.
The beneficial effect comprise that
Present invention achieves low electric energy consumption, and the problem that pipeline body will not be damaged, thus realize automation mechanized operation, be suitable for caliber in extensive range, improve work efficiency.Temperature is not higher than 70 degree, and pipeline body is not resulted in injury.Volume is little, lightweight, easy and simple to handle, it is simple to construction is carried, and efficiency is high, can operate continuously.Applied widely, do not limited by caliber.

The temperature of heating is not higher than 70 degree.
Described electromagnetic radiation plate 3 bottom is provided with rectangular waveguide.
Described spine 10 is high duty metal manufacture.
The frequency of described electromagnetic radiation plate 3 50 hertz, rated voltage 220-380V, voltage adaptation scope positive and negative 20%, rated power 4-40KW.
Above-mentioned embodiment is the preferred embodiments of the present invention; it is not for limiting the enforcement of the present invention and interest field; all equivalence changes made according to the content described in the present patent application scope of patent protection and modification, all should be included in scope of the present invention patent.
