The MERIT Foam Wiper Ball is engineered to wipe drill pipes or tubing strings wipe of cement, fluids, or debris. It is also highly effective as a mechanical barrier to separate different types of fluids during displacement operations.
Key Features and Benefits
- Superior Elasticity: Manufactured from premium natural rubber with a high parting stretch of 380% to 440%. This allows the ball to pass through significant restrictions without structural damage.
- Versatile Navigation: Designed for easy passage through internal upsets and restrictions, including mechanical setting tools, running tools, and diverters.
- Thermal Resilience: Suitable for extreme environments with an operational temperature range from 40°F to 302°F (4°C to 150°C).
- Chemical Compatibility: Proven performance with all types of drilling, completion, and displacement fluids.
