A scraping element for a pipeline pig, comprising:
- a moulded body having a circular peripheral scraping edge circumscribing the body and adapted to engage an interior surface of a pipeline;
- means for mounting the body to a pipeline pig;
- a wear resistant material embedded in the scraping edge of the body.
A scraping element for a pipeline pig, comprising:
- a disk-shaped body moulded out of urethane having a circular peripheral scraping edge circumscribing the body and adapted to engage an interior surface of a pipeline;
- means for mounting the body to a pipeline pig;
- a belt embedded in the scraping edge of the body, the belt being made from a wear-resistant material selected from a group consisting of an ultra high molecular weight polyethylene, a thermo-plastic, a thermo-set, a carbon-based material, kevlar, nylon, and ceramic, the belt having a plurality of upstanding ribs that serve as wear strips, the wear strips being positioned in parallel spaced relation around a circumference of the body.
