Heavy Weight Drill Pipe
Heavy weight drill pipe (HWDP) is used to make the transition between the drill collars and drill pipe. The function of the HWDP is to provide a flexible transition between the drill collars and the drill pipe, reduce the number of fatigue failures seen directly above the BHA, and also add additional weight to the drill bit. MMC Heavy Weight Drill Pipe is made of AISI 4145H and produced according to API SPEC7 and SY5146 Standard. The spiraled and slick design makes it useful in various applications. |
