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.

Classification of Pipe Pig！ 1. Fully coated polyurethane foam pig 2. Rubber pig ball 3. Cup pig 4. Dish cup straight plate pig + caliper aluminum plate 5. The two-way straight plate mechanical Pipe Pig 6. Two-way straight plate pig + diameter measuring aluminum plate (90% inner diameter) 7. Pressure control cup pig 8. Straight plate nylon brush pig 9. Two-way straight plate magnet pig 10. All polyurethane soft Pipe Pig

The Working Process of The Pig is As Follows: Stage 1: Product transmission. Stage 2: The pig is pushed into the product pipeline by compressed air. Stage 3: Pig return.

Pipeline damage Pipeline damage is usually the first indication of corrosion problems. However, in many cases. Such signs of pipeline damage will obviously exist for months or years. It’s just that people have been ignoring it. This damage may be minor (in the form of pinhole leakage). It can also be catastrophic. Because whether the water quality is damaged or the pipeline is replaced, it will bring significant economic losses.

In pipeline pigging, it is very necessary to understand the classification of pipes. Because only by understanding the performance and material of different pipes. So we can choose the type of pig according to this.

Foam pig is a cylinder with a tapered head made of foam rubber or foam plastic. The tail or surface is cross-wound and coated with various wear-resistant scraping materials. Mainly use pipes to clean and unblock. Today I will talk about the use and workflow of foam pigs.
