FIELD: machine building.
SUBSTANCE: invention relates to manufacturing of vacuum branch pipes for ship liquid media pipelines operating under pressure and vacuum or under vacuum only. The proposed branch pipe design implies that flat all-metal vacuum rings without hollows are rigidly connected to circular resin projections only by their flat surface of the inner diameter.
EFFECT: decreasing axial stiffness and enhancing operability and durability of branch pipe.
