Problems solved by technology
However, during the movement of the device in the pipeline, since the driving wheels are only located under the base and are not evenly distributed along the circumference, it is easy to cause the device to be inverted and cause the corrosion inhibitor coating to fail.

The invention discloses a corrosion inhibitor spray coating device for gathering and transportation pipelines and an operation method thereof, belonging to the field of anticorrosion of oil and gas storage and transportation pipelines. The device includes a pipe cleaner, a corrosion inhibitor liquid storage tank and a sprayer; the corrosion inhibitor liquid storage tank is used to store the corrosion inhibitor, and the remote control switch box installed at the front is used to control the air bag mechanism, so that the air bag pops up to ensure that the corrosion inhibitor is full Inside the nozzle, avoid spraying because the corrosion inhibitor cannot be pumped; the main body of the sprayer is a high-pressure gas storage bottle. A vacuum is formed at the outlet, so that the corrosion inhibitor is pumped and sprayed out to complete the spray coating of the corrosion inhibitor. The device rotates and moves in the pipeline through the sprayer, so that the corrosion inhibitor is evenly sprayed on the inner wall of the pipeline. The coating film is uniform and not damaged, and is suitable for marketing.
Description
Technical field [0001] The present invention belongs to the field of anti-corrosion technology of oil and gas storage transport pipelines, and is related to a spray coating apparatus apparatus for a collecting pipe, and its operational method thereof. Background technique [0002] In the gas field transfer pipe, since the gas is not treated, the gas often contains a large amount of acidic corrosive gas and high sulfur gas. When the effusion is produced, the acid liquid formed will have severe corrosion on the pipe. Crack the pipeline and perforation, resulting in a serious accident such as gas leakage and pipeline rupture. [0003] In order to slow down the corrosion of the transfer pipe, the corrosion inhibitor pre-coating film is often carried out, and the common method is used to carry the corrosion inhibitor and apply the corrosion inhibitor in the inner wall, but due to gravity, the coating film cannot be The corrosion inhibitor is applied to the top of the pipe, thereby cau...
