FloSafe Lock Mandrel

The FloSafe Lock Mandrel is a flow-secure locking device with a positive, confirmatory tell-tale mechanism in the FloSafe Running Tool, designed for the safe and correct deployment of Wireline Retrievable Safety Valves (WRSV).

The FloSafe Lock Mandrel is retrofittable to suit the uppermost “X” type nipple profile and prevents the possibility of unknowingly setting the WRSV incorrectly. The FloSafe Running Tool incorporates a positive, confirmatory shear pin tell-tale feature and in the event that the FloSafe Running Tool returns in the sheared position, the Expander Mandrel/Fish Neck has not fully travelled, indicating that the FloSafe Lock Mandrel has not fully set. To prevent FloSafe from opening and unseating the WRSV, the FloSafe incorporates a unique internal collet engagement feature which prevents the expander mandrel from opening during flowing conditions.
