The Critical Spillage Challenge
During kelly/pipe connection in oil & gas drilling/workover operations, residual drilling mud inside the kelly bar and upper drill string often sprays uncontrollably onto the drill floor. This causes:
1. HSE Hazards: Slippery surfaces increasing fall risks
2. Environmental Violations: Soil/water contamination from toxic mud
3. Operational Losses: $50-200/barrel mud waste + cleanup downtime
4. Equipment Corrosion: Accelerated degradation of rig components
How Mud Saver Valves Solve This
Installed below the kelly or lower kelly cock, these specialized valves automatically seal the drill string during connections:
1.Close instantly when the kelly is disconnected
2.Trap 100% residual mud inside the string
3.Reopen automatically when new pipe is connected
→ Eliminates spillage at the source
Key Technical Features
