SEALED PIPE CONNECTION TO BE USED IN OIL INDUSTRY, AND MANUFACTURING METHOD OF ABOVE MENTIONED CONNECTION Russian patent published in 2014 - IPC F16L15/04 

Abstract RU 2503874 C2

FIELD: machine building.

SUBSTANCE: first component includes a male end provided on its outer peripheral surface and containing a threaded zone sealing the surface, then, an end surface that ends with a support surface oriented radially relative to connection rotation axis. The second component includes a female end provided on its inner peripheral surface and containing a threaded zone sealing the surface, then, a cavity that ends on a support surface oriented radially relative to connection rotation axis. Threaded zone of the male end is crewed into threaded zone of the female end so that both sealing surfaces and support surfaces are in contact interaction, and space between end surface and the cavity can determine the volume that is at least partially filled with filler (M). Besides, a manufacturing method of the above connection is described.

EFFECT: higher reliability of the connection.
