As it is used to prevents the metal to metal friction between casing and drill pipes, limits drill string bending and reduces vibration caused by drill string rotation.
FEATURES AND BENEFITS
1. Positive protection against casing and riser wear during
drilling operations.
2. The Significant torque reduction created by our fluid
bearing design, with wear reduction around 20%, torque
reduction around 30%. And field-proven for improved
ROP.
3. Compatible with most oil, synthetic- and water-based
drilling fluids, having excellent acid/alkali resistance;
4. The wear sleeve is adopted with enhanced TFE material,
with temperature resistance up to 200 ℃,
5. The high wear resistance enable more than 500 hours
service time;
6. The product is simple structured, easy for onsite
installation, directly mounting it on the drill pipe.
Installation time: less than 1 minute.
7. On/off-site technical support and direction.
