Epiroc Introduces Pipe Support Centralizer for Pit Viper 231 Drills

New Pipe Support Centralizer improves drilling stability, hole quality, and drill string reliability.  www.epiroc.com Epiroc has launched a Pipe Support Centralizer for its Pit Viper 231 rotary blasthole drill rigs to enhance drill string stability and drilling accuracy. The Pipe Support Centralizer is an engineered drilling attachment for the Pit Viper 231 platform, compatible with both diesel and electric drill configurations. Designed to provide lateral support to the drill pipe, the system minimizes pipe deflection under elevated pulldown loads to improve borehole geometry, maintain penetration consistency, and limit component wear across the drill string. Rig Control System Integration and Automation The centralizer integrates directly with Epiroc's proprietary Rig Control System (RCS) to operate automatically across drilling cycles. The assembly utilizes a hydraulically actuated swing arm paired with a dynamic jaw mechanism that engages to stabilize the pipe as required. Integrated sensors and safety interlocks govern the mechanical deployment to ensure operational safety. Operators can also manually control the swing arm and jaw mechanism via the RCS display interface during maintenance procedures and system diagnostics. The resulting reduction in vibration and misalignment supports automated drilling sequences managed by the RCS software architecture. Maintenance and Field Availability By mitigating bending stresses and vibration during demanding drilling conditions, the centralizer reduces premature drill pipe fatigue, lowering replacement frequency and associated machine downtime. The Pipe Support Centralizer is available as a factory-installed configuration on new Pit Viper 231 diesel and electric machines, as well as an aftermarket retrofit kit for operational compatible units. Additional Context This section details technical specifications not included in the original news release. The Pit Viper 231 is a single-pass rotary blasthole drill designed to drill hole diameters ranging from 152 mm to 250 mm (6 inches to 9.875 inches) down to single-pass depths of up to 16.1 meters (53 feet). The rig delivers up to 236 kN (53,000 lbf) of bit pulldown force and a maximum dynamic breakout torque of approximately 10.8 kNm. During single-pass rotary drilling, long unconstrained lengths of drill steel are prone to column buckling, lateral harmonic vibration, and angular deflection when high feed force is applied against hard rock strata. The hydraulic centralizer acts as an intermediate guide bushing, reducing the effective unbraced column length of the drill string to maintain axial bit alignment. Epiroc Rig Control System (RCS) communicates via a CANbus network architecture to interlock centralizer jaw actuation with carousel indexing, mast inclination sensors, and rotary head travel limits, preventing mechanical interference during rapid rod hoisting or steel changes.
