Kelly

Yes! I am interested
FOB Price : Get Price

The kelly is a square, hexagonal or octagonal shaped tubing that is inserted through and is an integral part of the rotary table that moves freely vertically while the rotary table turns it.The upper end of the kelly is screwed into the swivel, using a left-hand thread to preclude loosening from the right-hand torque applied below. The kelly typically is about 10 ft longer than the drill pipe segments, thus leaving a portion of newly drilled hole open below the bit after a new length of pipe has been added and the drill string has been lowered until the kelly bushing engages again in the rotary table.
