摘要： A coupling (10) for a threaded and coupled connector used to secure the ends of the tubular pipe sections together comprising a tubular coupling body (11) with axially extending, internally threaded areas (11a, 11b) at each end of the body (11). Tapering external surfaces (11h, 11f) are formed on the body (11) which extend from a central portion of the body (11) toward each end of the body (11) and reduce in diameter in an axial direction from the central portion. The taper length (11h, 11f) is functionally related to the minimum outside diameter of a pipe section (12) to which the coupling is to connect.

摘要： A heavy weight drill pipe member is disclosed for use in drilling high angle and horizontal well bores in a corrosive environment. The heavy weight drill pipe member consists of a tubular member (10) with a longitudinal bore (29) therethrough, and includes connectors or tool joints (20, 22) attached at each distal end for connecting additional heavy weight drill pipe members. The tubular member (10) and tool joints (20, 22) are preheated, water quenched and tempered to obtain a unique combination of hardness, a yield strength and impact strength for improved resistance to stress corrosion cracking and hydrogen embrittlement in a hydrogen sulfide environment. The tubular member (10) includes a plurality of wear pads or protectors (12, 14, 16) equidistantly spaced along the longitudinal axis of the tubular member (10) to reduce bending stress in the pipe by limiting the degree of bend when the pipe is placed in compression in a high angle well bore. To reduce the chances of differential pressure sticking of the pipe when the pipe is used in high angle or horizontal well bores, each wear pad or protector (12, 14, 16) is provided with spiral grooves (24) therein. Each wear pad or protector (12, 14, 16) may also be hard faced or hard banded to reduce wear.
