LOCK WASHER-LOCKER FOR NIPPLE CONNECTIONS OF PIPELINES Russian patent published in 2020 - IPC F16B39/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in nipple connections of pipelines, in particular, in production of aircraft engines, which external tying consists of a large number of similar connections. Assemblage of the assembly is as follows: washer-locker 2 is put on feedthrough 1, nipple 3 with pipe 6 welded by welding 5 is placed on the cone of feedthrough and tightened by nut 4, at that, the connecting radius of washer-locker 2 plates is partially swollen. After tightening of nut 4, each of plates of locker 2 is bent to three faces of corresponding hexahedrons, thus mutual arrest of two hexahedrons takes place.

EFFECT: increased purity on assembly, reliability of locking of a nipple connection, as well as increased efficiency by reducing the number of technological actions at connection fixation.
