Faced with the new challenge of black powder, ROSEN has developed a new cleaning system which is especially effective in dry gas lines.

Combining the advantages of regular cleaning tools with those of magnetic inspection tools, the new technological approach also incorporates a specifically developed bypass system. Carried by support wheels to prevent wear of wall-touching components, the tool is sealed with polyurethane guiding and sealing discs. To improve cleaning capability, the tool is equipped with spring-supported magnetic brushes. All these mechanical components can be adapted to any pipeline properties, thereby optimizing cleaning efficiency under a wide range of different conditions.

To monitor overall performance and function, each tool is equipped with the ROSEN Pipeline Data Logger (PDL) data acquisition system. The Data Logger measures temperature, absolute and differential pressure, and acceleration in three orthogonal directions with one data triple per second (minimum, maximum, average). To get a maximum of information about the differential pressures, two PDLs are used for each cleaning tool.
