ABSTRACT:
A flange connection for connection in series hollow cylinder barrels forming a screw press. The cylinder barrel is formed with a groove adjacent one end thereof, and radially reduced, stepped portions of flange ring halves are positioned in the groove. Bore holes are formed at the abutment line between the flange ring halves and the external surface of the barrel, and pins are inserted in the bore holes. In this manner, radial, axial and rotative movement of the ring half is prevented, without the need for welding or otherwise permanently securing the connection.
