ABSTRACT:
A pipeline scraper comprising an elongated scraper body of preferably elastomeric solid material, having at least one annular sealing surface on both sides of a section having a smaller diameter, the distance between the sealing surfaces being equal to or smaller than the internal diameter of the pipeline, whereby on both sides of the section having a smaller diameter, at least one annular ridge-like, radial lip is provided which has a height which is at most a fifth to a tenth of the radius of the scraper body in the area of the sealing lip, with the distance of the scraper body from the pipeline in the area of the sealing lip corresponding to the 0.5- to 0.75-fold of the height of the lip and the sealing lip being formed and dimensioned such that upon getting into contact with the pipeline wall it is deflected and bent-off, respectively, such that the associated edge and the lateral face of the sealing lip get into contact with the pipeline wall, however, still leave a space to the scraper body.
