KELLY
The square and hexagonal Kelly is available up to 46 feet long. The Kelly is made from 4145H modified alloy bars that are quenched and tempered full length. A hardness range of 285 to 341 BHN and a minimum impact value of 40ft-lbs are maintained one inch below the surface at room temperature. All ends and center drive sections-trepanned to provide true bores. They are drifted to API specifications, and all connections are machined. The Kelly that we supply is stamped with the API monogram.
