Filling, emptying, separating

PSI foam pigs are ideal tools for filling and emptying processes during hydrostatic tests and liquid transport as well as when separating different media types transported through the same pipeline.

Drying

After pressure-testing (hydrostatic tests) the pipes need to be thoroughly dried, 
especially gas pipes. Low density, open pored PSI foam pigs are highly suitable 
for this task.

Cleaning

PSI foam pigs remove media residue from pipelines with great cleaning performance and also remove rust, deposits of various kinds and foreign bodies. PS foam pigs can be supplied in various densities and sizes from 2" to 48". Larger sizes up to 64" upon request. All types of pigs are resistant to oil, petrol methanol and other chemicals in accordance with the PSI chemical  resistance tables.
