pigging – cleaning of long pipelines

Thanks to the possibility of connecting few Double-Pigging Units together we are able to clean pipelines of length up to 100 km. This technology is mainly used in case of long, welded, often underground pipelines or in case of hard sediments and when the time of work execution is really short. Pigging of pipelines is conducted in closed circuit what is extremely significant for the environment protection. The waste after industrial cleaning, including the dangerous one, is safely utilized according to the existing regulations.
