Casing Wearing Sub
The Non-rotary Casing Wear sub consists of body, non-rotary sleeve, retainer ring and screws. The interface between integral body and non-rotary sleeve is coated hardness chrome for corrosion and abrasion resistance. The joint may reduce the friction between drill pipe and casing during drilling, and may reduce the loss of torque. So it is useful for preventing casing and drill pipe from tear and wear.
