Kellys

Our company offers square and hexagonal kellys. Kellys are available up to 46 feet long. Our kellys are made from 4145H modified alloy bars which are quenched and tempered in the full processing course. 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 precise bores. They are drifted to API specifications, and all connections are machined. Kellys are all stamped with the API monogram.
