What are the methods of pipeline cleaning?

There are two main methods for pipeline cleaning: one is chemical cleaning. The second is physical cleaning. Different methods have different advantages and disadvantages. Let's give you a brief introduction: 1. Chemical Cleaning Chemical cleaning is a cleaning process of degreasing, derusting, descaling and decoking industrial equipment, pipelines and containers by using chemical agents and certain technological means. It mainly includes chemical cleaning of oil field water injection pipe network, decoking cleaning of rectification tower, chemical cleaning of oil-to-gas long-distance pipeline, cleaning of industrial pipeline before use, etc. Before cleaning, cleaning agents should be selected for different equipment, and corresponding technical construction schemes should be formulated when cleaning pipelines under high pressure to achieve the best cleaning effect. Second, physical cleaning 1. Cleaning pipes with high-pressure water jet belongs to physical cleaning. High-pressure water jet cleaning is a high-speed water jet formed by the water pressurized by the pressurization system of equipment spraying from the nozzle. This kind of water jet has high impact and development ability, can remove scale, metal oxide and other attachments on the pipe wall, and has good cleaning quality. High-pressure water jet cleaning technology has the following advantages: it has a wide range of applications, not only for cleaning pipelines, but also for cleaning industrial equipment (such as heat exchangers, boilers, towers, storage tanks, etc.). ); No corrosion to pipeline equipment, no pollution to the environment, and the generated sewage is easy to treat. Zhongtuo company imported high-pressure water jet cleaning equipment from URACA company in Germany, and its excellent performance and good cleaning effect are favored by our customers. 2。 Cleaning of pig physical pipeline: The cleaning system of pig pipeline is mainly composed of pig, pig launcher, pig receiver, related detection system, power supply and driving medium. The pig is sent into the pipeline through the transmitter, and the flowing medium is used to push the pig and pig facilities to remove the dirt in the pipeline. In the process of operation, a double-gap jet and scraper are generated through the gap of the pig, and the pipeline is scraped mechanically at the same time, so as to achieve the purpose of scale removal.
