New Rod System to be Unveiled at CONEXPO-CON/AGG Adapted from a Press Release by Rockmore International Rockmore International will officially unveil its new Vector Rod System to the North American con- struction and aggregate industries at the upcoming CONEXPO-CON/AGG 2017 exhibition in Las Vegas, Nevada, this month. After several years of intense research and development, followed by monitored field tests in var- ious ground conditions, Rockmore engineers developed a new thread design, XT, for the Vector Rod System. The new design incorporates revolutionary new guided cylindrical contact zones between the male and female thread joints. These guided surface features are located in the nose and rear of the thread connections, and serve various benefits and improvements over traditional threads. The XT thread profile is based on the traditional trapezoidal “T” thread design and is there- fore compatible with industry standard thread types such as T38, T45, and T51. Thus, one can interchange and connect standard “T” style threaded components with the new XT thread, al- though the guiding advantages would be neglected. For example, a T45 threaded bit or shank adapter can be connected to a XT45 threaded rod with full compatibility. To achieve the full engineered benefits of the XT thread, however, one must consider the drill string as a system of connections between the shank adapter, rods, and the bit in extension drilling applications. Thus, the XT thread design employed in the Vector Rod System en- ables many performance and reliability benefits leading to major overall cost savings in the drilling cycle. “We specifically targeted to increase thread service life while enhancing drilling performance in extension drilling applications,” said Pejman Eghdami, executive vice president of Rockmore International, in explaining the goal of developing the Vector Rod System. The dual cylindrical contact zones in the nose and rear of the XT threads significantly increase the lateral support between thread joints and stabilize the connections with more rigidity to provide better energy transfer. The enhanced thread support and geometry extends thread life and increases the overall component service life of the shank adapters, rods, and bits with XT threads comprising the Vector Rod System. Because the XT thread guide feature improves thread alignment, the impact duration when “rattling” rods, as required in uncoupling connections, is minimized. This leads to lower wasted energy transmission, cooler couplings on rods, and ultimately to longer rod life. Thread grease is also better retained on the thread pitches resulting from the new XT geometry, further increasing thread life in all XT components.
