摘要:
The invention concerns a pig scraper for cleaning the inside wall of a coating agent conduit. The pig scraper includes a body insertable in the conduit and at least one sealing lip that seals against the inside wall of the conduit and extends parallel to a longitudinal axis of the body. A space is defined between the sealing lip and the body to form a pocket for enhancing the sealing of the sealing lip with respect to the conduit. The length of the sealing lip substantially prevents the lip from folding over on itself in response to a change in the direction of movement of the pig scraper in the conduit.
