Compared with other rolled straight thread connection joints, the stripped rib rolled straight thread connection joint has the following characteristics:

① Good thread profile, high precision, and smooth tooth surface;

②The diameter of the thread is consistent, easy to assemble, and the connection quality is stable and reliable;

③The service life of the thread rolling wheel is long, and the additional cost of the joint is low. The thread rolling wheel can process 5000-8000 thread ends, which is more than direct rolling.

The lifespan is increased by 3 to 5 times;

④The joint has passed 2 million fatigue strength tests, and there is no damage at the joint;

⑤ Tested at -40ºC low temperature, the joint can still reach the same strength as the base metal, and has good low temperature resistance.
