What is the difference between dredging and cleaning of pipeline?

As the name implies, pipeline dredging is to dredge the inside of a blocked pipeline through certain professional equipment. The pipeline cleaning can be to clean the surface of the pipeline, or use a high-pressure water gun to clean the inside of the pipeline.

At present, the commonly used pipeline maintenance methods are pipeline dredging and cleaning. The cleaning specifically uses some effective measures to improve the head difference in the pipeline, increase the water flow pressure, increase the flow velocity and flow rate to clean the pipeline sediments. There are mainly two types of hydraulic flushing and mechanical flushing.

Dredging is a method that needs to be used when there are too many silt deposits in the pipeline or even cause clogging. When dredging operations are required, mechanical action should be applied to the sediments to make them loose and carried by the sewage or directly removed manually pipeline. At present, the main dredging methods are manpower dredging, bamboo dredging, winch dredging, and drill pipe dredging, etc., and the use should depend on the actual situation.
