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 sections of the clean sweep line test pressure: removal of debris, rust, 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.

In the operation of the pipeline, according to the requirements of the operation of the corresponding series of pipe cleaning device. Clear edge tube cup and the inner wall of the pipeline elastic sealing, caused by pipe conveying medium pressure as the driving force to promote the Qing run along the pipeline tube. Rely on the pig itself or the machine with scraping and scouring action to clear the pipeline scaling or sediment. Is made of polyurethane raw material by the mold or foam plastic through the special equipment processing, the first end of the tube with a conical head of the garden, its external coating cross winding wear resistant layer or carbide of the hard wear-resistant belt. The core material is soft, easy to pass the 90 degree of curvature radius of the elbow, and the tube wall close fit, you can remove dirt and corrosion in the pipe and other impurities.
