Casing Scraper
Features of Casing Scraper:
- Applied to remove the substances, such as cement, mud, embedded bullets, rust, mill scale, paraffin, perforation burrs, etc., attached to the inner wall of casing so as to keep it clean and ensure normal drilling operation;
- Forged with high quality steel and subject to heat treatment;
- The scraper blades fitted into the grooves of the scraper body and safely held by a dovetail keeper and spacer;
- An enduring service life ensured by left helical grooves on the blades and hard-faced blade edge;
- With enough blades fitted in the scraper body, the casing inner wall can be overall and completely scrapped even without rotating the scraper body;
- Easy to be installed in the drilling string between the bit and the bit sub with API REG connection thread;
- Bits, running below the scraper, serving as a guide and to prevent the circulation hole through the scraper from being plugged;
