• Tri-Spiral™ HWDP


    Grant Prideco developed Tri-Spiral Heavy Weight Drill Pipe for applications where standard heavy weight drill pipe can fail-extended reach or horizontal drilling. The severe bending stresses and hole-wall contact are reduced by three spiral upsets that are equally spaced between tool joints. The upset design helps reduce buckling and differential sticking, as well as torque and drag. Spiraling the upsets also helps move the cuttings off the low side of the hole for better hole cleaning.

    Tri-Spiral Heavy Weight Drill Pipe features more weight per joint and better hole cleaning characteristics than standard heavy weight drill pipe, providing optimum performance in severe drilling conditions.
