​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.

Gas pipeline pig is specialized devices developed for the pipeline industry with the primary purpose of performing maintenance and inspection tasks within the pipeline. The term “pig” is an acronym that stands for Pipeline Inspection Gauge, and these devices have been a cornerstone in the pipeline industry for years, being used in various applications, from oil and gas to chemical and water pipelines.

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 pigs operate on a simple yet efficient principle, utilizing the pressure differential within the pipeline to perform various maintenance tasks. Initially, they are introduced into the pipeline through a pig launcher and are propelled by the force of the flowing product or an external driver such as compressed air or water.

Pig tracking equipment is critical for monitoring and maintaining pipelines in many industries, including oil and gas, transportation, and infrastructure maintenance.

The cleaning ability of Disc Solid Cast Pig is very good. Compared with a mechanical pig, its main material is also polyurethane. It means its passing ability at the bottom of the pipeline is much better than that of the mechanical pig.

During the transportation of products in the pipeline, the pigging system is a system that uses Decoking Pig or scraper ball equipment to perform various pigging systems. or the practice of product recovery or maintenance operations. The advantage of using a pigging system is that there is no need to stop the flow of products in the pipeline. This can also achieve the desired effect of the manufacturer. These devices are called pigs. This is because they scrape or clean like normal pigs.
