Total Depth Tools offers a full line of new and used Heavy Weight Drill Pipe (HWDP) in nominal sizes from 3 1/2" to 6 5/8".
HWDP is another component of the drill string that acts as a gradual transition between the heavy, stiff drill collar and the flexible drill pipe. HWDP helps prevent undue stress concentrations in the drill pipe by improving the Bending Stress Ratios in the drill string. Without the use of HWDP, the drill pipe would be at a substantial risk of fatigue.
HWDP is most commonly used in the process of horizontal drilling to helps to prevent differential sticking, reduce buckling, and control torque. HWDP is a vital part of the drill string and is heavily recommended to minimize the operational risks relating to downhole failure.
We have a vast inventory of new and used HWDP in standard (slick) and spiral options. If we don't have what you are looking for, we can order it new from our manufacturing partners domestic and abroad. Please contact us for any new/used HWDP inquiries.
