Based on API thread form design, lower processing cost;

In addition to the other high torque threads, the JSHET series thread trimming and the subsequent maintenance cost are low, except for the equivalence.

JSHET series screw, site construction, simple operation, saving time shackle;

JSHET rationalization design, increase the service life of the thread;

JSHET series thread is a high torque thread connection developed and designed based on API screw structure according to the feedback from field drills of drilling contractors. It is widely used in ultra deep wells, extended reach wells, horizontal wells and other well conditions.


JSHET has a good interchangeability in the market, and can be interchangeable with the special buckles of the MT series and the CET series.
