The type of the premium thread connection also are different, all of them have its features.Today I will give you an introduction for one kind of the premium connection named Fox.

Fox is a kind of advanced premium threaded connection for tubing, casing and line pipe. Its innovative thread geometry achieves substantial reductions in peak tooth loading both on make-up and in tension.The patented triple radius contour seal ensures superior over torque resistance and greatly increased seal stored energy. The result is a significantly reduced tendency to thread galling, combined with outstanding performance even under extreme loading and rapid temperature change conditions.
Threaded line pipe requires high fatigue performance under long term exposure to cyclic bending in combination with internal and external pressure and axial loading. FOX premium connection has been well proven in use worldwide.
