Tri-spiral HWDP

JSH, as per customer’s requirements, design and manufacture Tri-Spiral™ Heavyweight Drill Pipe for extended reach and horizontal drilling applications requiring greater buckling resistance and hole cleaning than is available with standard HWDP. 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 HWDP features   more weight per joint and better hole cleaning characteristics than standard heavyweight drill pipe, providing optimum performance in severe drilling conditions.
