1. Natural gas pipelines in operation: remove corrosive substances such as accumulated water, light oil, methane hydrate, iron oxide, carbide dust, carbon disulfide, hydrogen sulfuric acid, etc.; reduce the corrosion damage of corrosive substances to the inner wall of the pipeline; re-clarify Pipeline direction; detect pipeline deformation; check the integrity rate of valves along the line; reduce working backpressure.
2. Crude oil pipelines in operation: pigging before inspection in the pipeline, and pigging of oil pipelines in low-volume intermittent operation; removing oil condensate, waxing, and scaling inside the pipeline to reduce oil back pressure and friction, The purpose of lowering the oil temperature.
3. Chemical materials and edible oil pipelines: clean up pipelines with polymerization materials; isolate different pipelines to realize single-pipe multi-product transportation and metering pipe transportation.
New pipeline pigging:
4. Sectional pigging and sweeping line pressure test: remove pipeline debris, rust, drainage, and exhaust.
5. General pigging and pressure test: detecting pipeline deformation and construction quality. Exhaust before the hydraulic test, drain before production, dry, and isolate media.
6. Water delivery and injection pipelines: remove scale and sediment.
