Tubing Coupling

Size

Our tubing coupling is a type of oilfield drilling tool for the connection of tubing. It can effectively solve the problem of fatigue fracture that is easily caused by the stress concentration of the available product. Our company is specialized in producing the oil pipe with the outer diameter range from 60.32 to 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.
