A. Good balance between antiwear andfriction-reduction
B. The wear rate is less than 6% ofthat of bare tool joint, which can prolong 3 times of the
tool joint servicelife
C. Good property offriction-reduction, which can reduce the casing wear to the least, and its
wear to casing is less than 11%of that of bare tool joint
D. Reduce the torque of drillingstring
E. Good weldablity with little splashand good rewelding preformance
F. Friendly toenvironment
