CONNECTION BETWEEN TWO PIPELINE COMPONENTS Russian patent published in 2015 - IPC F16L37/244 

FIELD: machine building.

SUBSTANCE: invention relates to the connection between two pipeline components. One pipeline component contains the male end part, and the another pipeline component contains the female end part. Two pipeline components can be connected together by means of the male end part installation in the female end part such, that the pipeline components rotate relatively to each other during their connection. At least one end part of one pipeline component is made at least with one shoulder, and at least one end part of the other pipeline element is made with the appropriate groove such that the shoulder and groove lock the pipeline components in proper position relatively to each other. The shoulder is installed on the external periphery of the pipeline component, thus the shoulder is manipulated from outside of the pipeline component.

EFFECT: invention improves reliability of the connection.
