In cementing and pumping operations, preventive maintenance like continuous greasing is essential to ensure smooth operation. However, a complete valve disassembly and overhaul is never random.
It is driven by specific technical conditions:
- Leakage: The primary reason for losing pressure integrity, requiring seal replacement.
- Valve Seizure: When opening and closing becomes extremely difficult even after greasing, usually caused by heavy buildup or friction.
- Internal Scoring & Pitting: Surface wear and scratches on the plug body due to the abrasive
nature of cement slurry. - Seals Degradation: Loss of O-rings flexibility due to heavy usage and chemical exposure.
Knowing when to rely on preventive care versus when to execute a complete overhaul is what drives operational reliability and safety!
