The cleaning pipe system is composed of a pipe cleaner, a transmitting and receiving device, a receiving device, and an electronic tracking and cleaning device. Pigging is pipeline cleaning tools for scraping wall dirt. During the operation, the pig in the pipeline, the outer edge of the cleaning tube and the inner wall of the pipeline to form a good elastic seal, using the pipe from the medium pressure is the force, push the pig operates in the pipe tube, the leather bowl, steel brush and other components of pig itself has to interact with the inner wall of the pipe in order to achieve the purpose of cleaning pipe, at the same time, the pig itself carries a super low frequency transmitter and ground instrument matched, at any time can understand the operation of cleaning pipe in the pipe; the ball receiving cylinder are respectively installed on the pipeline at the beginning and end of Qing Dynasty, used to send and receive pigging; electronic tracking pigging a set of instruments including positioning, positioning receiver, transmitter, line ball indicator instrument, used for tracking operation in the pipeline pigging ball, once stuck in precise positioning.

Natural gas pipeline 1 operations: clear the pipeline internal water, light oil, methane hydrate, ferric oxide, carbide dust, carbon disulfide and hydrogen sulfate and other corrosive substances; reduce the corrosion damage of corrosive substances on the inner wall of the pipe; to clear the pipeline to inspect pipe deformation; check valve; intact rate along; decrease working backpressure.

2 line: operation in Central China pipeline detection before the tube, low throughput intermittent operation of oil pipeline; pipeline internal clearance of condensate oil, wax and scaling, to reduce backpressure and wear resistance, reduce the temperature of the oil.

3 chemical material and edible oil lines: clean the pipe with polymerized materials; isolate different pipeline medium medium conveyance and measure pipe conveying pipe. New pipeline cleaning:

4 section clean sweep line test pressure: remove the pipeline debris, rust, drainage, exhaust.

5 total pass clear pipe pressure test: detection of pipeline deformation, construction quality. Exhaust before water pressure test, water drainage, dry, medium isolation.

6, water injection pipeline: remove scale and sediment.

Type of pig:

General rubber pipe cleaning ball, cup pig, straight pipe cleaner, scraping wax pigging, foam pig, buckling detector and other six series.
