Heavy Weight Drill Pipe The wall thickness of weighted drill pipe is between drill pipe and drill collar. Its structure is similar with drill pipe. It is made from premium alloyed steel. Its technical parameters meet with API Spec7-1 Standard.

Square Kelly is the main driver of the whole drill string. It transmits torsional energy from the rotary table through the drill string to the bit at the bottom of the hole. Our square Kelly is a long square, precision machined heavy steel bar that is supported by the swivel through the rotary table and is connected to the first joint of drill pipe in the drill string.
