Product Description
The serrated casing thread connection structure comprises A collar and a pipe body. The inner thread A of the collar and the outer thread B of the pipe are serrated thread links.
The value range of the tooth Angle of the serrated thread link tooth shape is set between 50 and 60°. The beneficial effect is that the serrated casing is threaded
The joint structure adopts a tooth-shaped zigzag structure with a tooth-shaped Angle, and the tooth base and top are small circular arcs. To prevent excessive concentration of mating contact stress,
Double taper design is adopted, which not only retains the advantages of round thread casing technology, good sealing, slip-resistant and strong,
It also overcomes the disadvantages of low anti-skid strength of round thread casing and poor sealing of partial trapezoidal thread casing.
Double taper design is significantly improve the profit state of thread contact, can effectively prevent the occurrence of gluing phenomenon, improve the performance of up and down.
This is conducive to well operation.
