Drying of pipelines
Cleaning pig Type-ST-A-4
Cleaning pigs or pigs of type ST-A-4 are used for cleaning pipelines or for pig cleaning of pressurized pipelines with medium-hard deposits in pressure pipelines. 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 bottom plate made of PUR (polyurethane) and a density of approximately 5-7 lbs/ft³ (soft) or 8-10 lbs/ft³ (hard).
