Tubing Coupling

114.30mm. The inner wall of product body is connected with the tubing end by means of tapered thread. The coupling end combines with the oil pipe by adoption of the same pitch of flat thread. In this way, our product can reduce the stress concentration that results from the connection between the single tapered thread and the external thread of oil pipe. It offers wonderful connection effect, and effectively prevents the tubing string from breaking off.

In addition, this tubing coupling provides extremely precise size, outstanding sealing performance, superior comprehensive mechanical properties, as well as strong corrosion resistance. Thus, it can be adapted to the complex operating state of the well drilling.
