FIELD: machine building.
SUBSTANCE: during the flare cap manufacturing upon assemblage of the flange and pipe the perpendicularity of the flange seating surface and pipe axis is ensured by flange welding to the pipe, and machining of the seating surface of flange assembled with the pipe, conicity and correspondence of the cone and cylindrical part are ensured by forming of the cone part by cone pressing over the cone surface under assemblage conditions and/or locking of the cylindrical part until ovality observation. At that rest parts are connected by welding and using thread joints.
EFFECT: stability of flare cap operation.
