Heavy Weight
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 also be used for running and landing casing.
