Heavy weight drill pipe are developed to provide a gradual transition from drill pipe to the relatively heavy weight drill pipe.It can reduce fatigue damage to the drill pipe.
Heavy weight drill pipe are intended for directional drilling.It improves directional control by reducing touque and drag.
Different sizes of heavy weight drill pipe are 3 1/2'',4'',4 1/2'',5'',5 1/2'' etc.
