PROFILE OF WEDGE-SHAPED THREAD, HAVING UNLOADING AREAS FOR THREADED SEALANT FROM TOPS TO HOLLOWS Russian patent published in 2022 - IPC F16L15/06 

FIELD: sealing.

SUBSTANCE: invention relates to a connection, which contains the first tubular element having the first profile of screw thread, formed by the first set of tops, hollows, and sidewalls of thread, while each sidewall of thread separates each top of thread of each hollow of thread. The connection also contains the second tubular element having the second profile of screw thread, formed by the second set of tops, hollows, and sidewalls of thread, while each sidewall of thread separates each top of thread from each hollow of thread. Tops and hollows of thread are essentially axial relatively to tubular elements, and sidewalls of thread are essentially radial relatively to tubular elements. The first tubular element and the second tubular element are made with the possibility of connection, when the first profile of thread engages with the second profile of thread. When connecting the first and the second tubular elements, between the first set of tops of thread and the second set of hollows of thread, and between the second set of tops of thread and the first set of hollows of thread, unloading spaces for a threaded sealant are formed.

EFFECT: invention provides a significantly larger volume for unloading a threaded sealant.
