Torque Rings are the steel rings inserted into the couplings to upgrade the API connections for both oil tubing pipe and casing pipe. Torque ring provides mechanical shoulder for the ends of the pin ends to increase torque capacity. By creating a positive shoulder, API pipe can be run, and rotated at a significantly greater torque.
Puyang Zhongshi Group produce torque rings for use in drilling and production operations for both casing and tubing, which provide the premium performance for API connections. We also supply the installation tool for torque rings.
