Selection Guide
Example of Pig Selection Grouping
Pig selection criteria vary widely depending on the intended application.
However, selecting a suitable pig based on the following key factors can provide significant performance benefits.
1. Cleaning efficiency per run
For cleaning newly installed pipelines, this factor greatly affects the construction period and overall cost.
2. Sealing performance
During dual-fluid separation or evacuation operations, fluid mixing (contamination) can result in significant economic losses and additional operating costs.
3. Selection of long-life products
For long-distance pipelines, high-quality materials with excellent wear resistance and extended service life should be selected.
4. Chemical resistance
Materials with excellent chemical resistance should be used to ensure compatibility with various chemical fluids.
