FLANGE CONNECTOR Russian patent published in 2010 - IPC F16L23/02 

FIELD: machine building.

SUBSTANCE: each attachment point consists of pin with nut and sleeve enveloping pin and mounted on the latter resting on flange nearest to nut. Fastening elements, main and secondary pads with elements out of expanded graphite and channels for pads facilitate contact of flange surfaces during cogging of pads as a result of tightening not more, than half of pins with force corresponding to presence of nominal force in these pins upon tightening the rest of the pins. Also there is facilitated equal density of elements out of expanded graphite. The invention ensures convenient operation of the flange connector and its raised reliability.

EFFECT: raised uniformity of forces generated with pins at preliminary tightening and during operation, increased stability of tightening force.
