The pig pipe descaling method is a highly efficient physical cleaning technology, which mainly uses special pig tools to promote the dirt stripping in the pipeline. The following are the specific methods and characteristics:
First, the working principle
The pig uses the sealing parts of special materials to closely fit the inner wall of the pipeline, moves along the pipeline under the impetus of compressed air or water flow, and scrapes the attachments through mechanical friction such as steel brushes, scrapers, steel nails, and reinforcing steel nails configured by the pig to remove rust, calcium and magnesium scale and other deposits.
Second, technical characteristics
1. Adaptable
It can handle rust and scaling with different hardness and softness, and is suitable for pipes of various diameters, and can pass through complex structures such as 90-degree bends and T-joints.
2. Efficient and environmentally friendly
Tens of meters to tens of kilometers of pipelines can be cleaned in a single operation, without the need for chemicals, to avoid secondary pollution. Improve the efficiency of pipeline transportation, extend the service life of pipelines, reduce energy loss, and reduce economic losses
3. Multi-functional application
In addition to descaling, it can also be used for cleaning before the start-up of newly laid pipelines to ensure the initial cleanliness of the pipeline system and improve the purity of the conveying medium
