Bare foam pig selection method
The bare foam pig is a device used to clean oil pipelines and plays a very important role in pipeline cleaning and maintenance. So how do we choose when cleaning the pipeline? Next, we will introduce the selection method of the bare foam pig in detail, and I hope to help everyone. The details are as follows.
1. Full production
After the welding, pigging and pressure testing are completed in each section, the whole pipeline is cleaned before the whole line and replaced before production. It is recommended to use a pig with good sealing and long running distance. It is recommended that the order of the pigs be in order. :
2. Segment pigging
(1) Since it is the initial stage of pipeline construction, there are many soils left in the pipeline, metal scraps, welding, etc. It is recommended to use a pig with strong cleaning ability.
(2) Because it is the first cleaning, the situation inside the pipeline is more complicated. It is recommended to use a pig with good sealing performance and tracking device to determine the exact position of the pig when the pig is in the card, and take timely treatment. Measures.
(3) According to the above requirements and our long-term on-site practice and user feedback recommendations for comprehensive analysis, it is recommended that the order of pigs selected is:Two steel brush two-cup type pipe cleaner, one steel brush two-cup type pipe pig.
(4) When removing rust and chips, it is recommended that the order of the pigs be as follows: a scraper three-cup type pig, a four-cup type pig, and a three-cup type pig.
3. According to the special design requirements of the pipeline and other requirements of the owner and the construction unit, it is also possible to select a series of measuring pipe cleaners for measuring pipe deformation and magnetic type pigs for adsorbing fine fines.
The above is an introduction to the selection method of the bare foam pig. I hope that everyone can understand the selection method of the bare foam pig, which will help everyone.
