The machining tool of the ReSOLVE iX™ intelligent extreme wireline intervention service, combined with the SPRMB-063BVR ball valve remover bit, has been successfully qualified to address the challenge of reopening failed isolation valves. This innovative solution was applied to a 4.75-in chrome ball (Material: 101008013 - SST - SS420 - 13CR), enabling full penetration of the closed valve while capturing and retaining both coupons in a single operation.
The machining process achieved a 63-mm flow path using validated cutting modes, including constant pump rate, torque control, and WOB optimization. With real-time adjustments managed by the MillOptimizer™ autonomous milling system, the operation was completed efficiently, with a machining time of just 2 hours (1 hour per coupon). This solution demonstrates our commitment to delivering precision and reliability in challenging operational scenarios.
Isolation valves are critical components in various industrial systems, ensuring controlled flow and system integrity. However, when these valves fail or become obstructed, they can disrupt operations and pose significant challenges. In one such case, a 13Cr (80 KSI) ball valve required precision machining to restore functionality and reopen the flow path.
