Drying of pipelines
Cleaning pig Type ST-A-3
Cleaning pigs or pigs of type ST-A-3 are used for cleaning pipelines or for pig cleaning of pressurized pipelines with soft deposits or aggressive substances that should not come into contact with uncoated foam. Another application for our cleaning pigs is the cleaning of pressure pipes before the use of other cleaning pigs, disc pigs, or cup pigs. These cleaning pigs are made of polyurethane foam with a complete coating of PUR (polyurethane) and a density of approximately 5-7 lbs/ft³ (soft) or 8-10 lbs/ft³ (hard).
