High performance shoulder ring for tubes and other tubular articles in oil and gas industry

A coupled pipe connection system may include a coupling having an internal thread adapted to connect two pipe segments by threaded engagement of an external pipe thread with an internal coupling thread. A torque ring may be disposed within the coupling and between the first tube and the second tube. The torque ring may be an outer cylindrical surface, at least a portion of the outer cylindrical surface may include a plurality of tapered threads that engage and are tapered to fit the intermediate length axial section/J-space of the internal thread of the coupling. The annular surface of the torque ring may be angled inwardly or outwardly and adapted to mate engagement with a corresponding angled annular surface of the pipe end. And the torque rings with gradually reduced axial lengths can be gradually replaced out along with the increase of the assembly cycle times. The torque ring may be replaced with a coupling having an inner shoulder with a tapering axial length. 一种联接的管连接系统可以包括具有内螺纹的联接件，该联接件适于通过外部管螺纹与内部联接件
