Heavy weight drill pipe (HWDP) is similar in appearance to normal drill pipe with the exception of an upset area near the middle of the tube. Its wall thickness is 2-3 times that of normal weight drill pipe of the same size. The HWDP is used for additional weight and to help reduce fatigue in drill pipe by acting as a transition stiffness section between very stiff drill collars and very limber drill pipe. HWDP can be also used for running and landing casing.
