necessity of dredging sewage pipelines

long term use of pipelines will solidify the oil sludge and rust in the pipelines, resulting in smaller pipe diameters. The sludge in the pipe precipitates to produce hydrogen sulfide gas, which causes environmental pollution and is easy to cause combustion and explosion. The acid and alkali substances in the wastewater are easy to corrode the pipe wall. Foreign matters in the pipe will cause pipe blockage. The raw materials of pipes, steel pipes, steel plates, stainless steel, etc. will form mill scale during rolling, and rust, welding slag, oily rust inhibitor, thermal insulation materials and other impurities will form during the storage, transportation and installation of pipes

the above impurities seriously affect the normal use of the pipeline, so it is very important to clean the pipeline and restore the surface of the material in the pipeline. After cleaning, a dense chemical passivation film will be formed on the clean metal surface. The passivation film can effectively prevent the recurrence of dirt, effectively protect the equipment, ensure the safety of the equipment and prolong the service life of the equipment

there are tricks to dredge sewage pipelines

1. Chemical pipeline cleaning

chemical cleaning pipelines use chemical agents, and defoamer is a good choice, which has a very significant effect on sewage treatment. Carry out temporary reconstruction of the pipeline, and use temporary pipeline and circulating pump station to carry out circulating chemical cleaning from both ends of the pipeline. This technology has the characteristics of strong flexibility, no requirements for pipe shape, fast speed, thorough cleaning and so on

2. High pressure water cleaning

high pressure water jet above 50MPa is used to peel and clean the dirt on the inner surface of the pipeline. This technology is mainly used for short-distance pipelines, and the pipeline diameter must be more than 50cm. This technology has the characteristics of high speed and low cost

3. Pig type pipeline cleaning

pig industrial pigging technology relies on the driving force generated by the fluid driven by the pump to drive the pig (pig) forward in the pipeline, discharging the dirt accumulated in the pipeline out of the pipeline, so as to achieve the purpose of cleaning. This technology is widely used in all kinds of process pipelines, oil and gas transmission pipelines and other cleaning projects, especially for pipeline cleaning of long-distance fluid transmission, which has irreplaceable advantages of other technologies

the above is the introduction of the relevant contents of sewage pipe dredging, which I hope will be helpful to you. For more information about sewage pipe cleaning, please continue to pay attention to the information
