توضیحات
SMART drill collar and tool joint compound is a premium-quality, unleaded compound containing extreme pressure and anti wear
additives. SMART solids package is formulated to prevent excessive circumferential makeup by increasing the coefficient of friction under compressive forces. As stress levels rise above 50% of yield the friction factor increases, limiting downhole makeup. Full hydraulic joint efficiency is maintained allowing joint shoulder faces to mate completely without standoff or deformation.
-Not classified as a marine pollutant.
– Contains no Heavy metals.
– Extreme-pressure additives provide
additional protection against seizing and
galling and allow consistent make up.
– Complex grease base protects against rust
and corrosion.
-Sticks to wet joints.
-Unequaled resistance to makeup downhole.
-Approved for under-balanced drilling
applications.
For optimum performance on API drill string connections, SMART should be utilized with the torque charts in API RP7G or by contacting the drill pipe and connection manufacturer. Premium drill string connections such as HITORQUE(HT). Extreme Torque(XT) and XT-M connections, etc utilize make-up torques based upon thread compound friction factors of 1.0. Therefore, use the torque provided by the premium connection manufacturer. Adjusting make-up torque
based on thread compound friction factor may still be advised.
*Many factors such as pipe size, thread geometry, drilling mud contamination, etc. affect the friction factor. This is a relative number and in all applications experience and prior knowledge should be used to adjust make-up torque accordingly. Contact your drill pipe manufacturer for torque and friction related specifications.
