Orchid Energy Casing scraper is the tools for cleaning the dirt which may be left inside walls of casing, such as solid cement, sand,rag, hard wax, various salt crystals or burrs, so as to make all down hole tools pass through unblocked. Especially when a small circular clearance is available between the down hole tools and casing inside diameter, the complete scrapping becomes more necessary before working.Before order,please tell us casing scraper size or model;casing scraper thread connections, if nonstandard;casing size and weight;
