Application of Pig in the Cleaning of Pressure Drainage Pipelines
Pressure drainage pipelines are pipelines for pressure conveying industrial drainage and domestic drainage,that are set all over the industrial production and urban life.After long-term operation,the inner wall of drainage pipelines will appear impurity deposition adhesion,scaling,microbial growth and other problems,shorten the service life of the pipelines,reduce the conveying capacity,increase the operating costs,so it is essential to regularly clean the pipelines.Combined with the cleaning process of pressure drainage pipelines in cold rolling process,the application ef-fect of pig in pressure drainage pipeline cleaning operation is analyzed.
