Any pipe that does not conform to the inspection at any time will be separated from the batch. Holly Pipe can recondition HDD and utility drill pipe through a process we are very familiar with. We can buildup and hardband drill pipe, refurbish connections, or re-tool joint the ends of HDD pipe. Refurbishing drill pipe and subs is a specialty of Holly Pipe, and we welcome the opportunity to help drillers drive ahead with premium reconditioned tools. Holly Pipe can recondition HDD and utility drill pipe through cleaning, inspecting, rethreading and bucking on new connections in order to bring the drill pipe back to the exact length. To ensure accuracy while loading mini-HDD machine racks, it is important that the length of the drill pipe is consistent and exact. Horizontal directional drilling (HDD) tubulars, also referred to as drill rod or utility drill pipe, is smaller compared to oilfield tubulars and is available in standard lengths of 6’, 10’, 15’ and 20’. Holly Pipe can help you determine the appropriate heavy weight drill pipe for your project from size 2 7/8” to 6 5/8” with hardbanding, spiral grooves or special threading. Heavy weight drill pipe is also utilized in the horizontal directional drilling (HDD) industry for added strength in high stress situations.
Heavy weight drill pipe (HWDP) is usually run in between the drill collars and the drill pipe in order to prevent fatigue of the drill pipe in the vertical drilling industry. We offer 3 1/8” to 11” steel or nonmagnetic drill collars with spiral, slick, slip recess, elevator groove, hardbanding, bore-back on box or special threading. Holly Pipe is committed to serving all drilling industries and will meet or exceed customer specifications for drill collars and other drilling tubulars. Maximum load to buckle 30’ (push): 80,000 ft/lbsĭrill collars play a heavy role in today’s world of drilling.Maximum torque to yield (twist): 80,000 ft/lbs.The DS-50 connection combined with the classic 6 5/8” tubing provides tremendous strength and durability.
