​As one of the most basic methods of corrosion monitoring, corrosion coupon monitoring has the characteristics of simple operation and high data reliability, and can be used as an important basis for equipment and pipeline material selection. At present, there are two main methods of corrosion coupon technology used in Shengli Refinery.

Corrosion poses a significant threat to the safe and efficient operation of refinery equipment, as it can lead to equipment failures, leaks, and even accidents such as fires and explosions. To address this issue, refineries employ various Corrosion Monitoring Methods.

Pipeline magnetic pig is a mechanical pig equipped with strong magnets. He can clean the iron filings from the pipe. At the same time, it can also help to position the pig in the pipeline. If the space of the pipe is also very limited. It can also be molded into a polyurethane pig or a disc molded into polyurethane. Magnetic pig has many uses. Among them, its main purpose is to collect iron-containing debris inside the newly put into the production pipeline. Such as welding rods, weld slag, mill scale and rust. It can also carry out continuous cleaning activities. They can also activate electromagnetic equipment on the pipeline. For example, valve, annunciator, and switch. So if you want to know more about Magnetic pig, please contact our professionals to answer them for you.

Pipeline oil leakage is a serious risk during pigging. Although there are various reasons for pipeline oil leakage. But generally speaking, it mainly includes the following two aspects: First, after long-term corrosion of the pipe body, there are thin parts in the severely corroded parts. The thin part of pipe wall may be broken during ball passing. There is also a risk of oil leakage from the pipeline.

The cleaning of the pipeline is to dredge the pipeline, clean up the sludge in the pipeline and keep it unblocked for a long time, so as to prevent waterlogging in the city. Water Treatment Pipeline cleaning has become an important work that Drainage Department should pay more attentions. In the drainage pipeline, a large number of sundries and cement sand at the infrastructure construction site will precipitate and deposit, which will cause pipeline blockage. Without the cleaning of pipelines, it will cause excessive flow of sewage, pollute the environment and bring trouble to people’s life.
