On the premise of not changing the thread shape,the size of the joint is increased by upsetting process,the connection strength is improved,and the requirements of the lower depth are met.There is a gap of 0.076mm between the tooth top and the tooth bottom of the external thick oil pipe.When tightening the thread,the tooth top gap is full of thread grease,and the leakage channel is blocked after the thread grease solidifies,so as to achieve the sealing effect.
