A FLANGE ELEMENT, A FLANGE CONNECTION COMPRISING SUCH FLANGE ELEMENTS AND A TOWER STRUCTURE

摘要

A flange element (20, 50, 74) for a flange connection (92) with a longitudinal centre axis A is disclosed where the flange element (20, 50, 74) comprises a flange part (21, 51, 75) having a front side (29, 59, 83) with a front surface (30, 60, 84). The flange part (21, 51, 75) is provided with a flange wedge (32, 62, 86) comprising a flange wedge surface (33, 63, 87) that is part of the front surface (30, 60, 84), and a flange heel (34, 64, 88) comprising a flange heel surface (35, 65, 89) that is part of the front surface (30, 60, 84). The flange wedge surface (33, 63, 87) makes a wedge surface angle α1 and the flange heel surface (35, 65, 89) makes a heel surface angle β with a plane P that is perpendicular to the longitudinal centre axis A of the flange element (20, 50, 74). There is also disclosed a flange connection (92) comprising two flange elements (20, 50, 74) and a tower structure (16) comprising at least two tower sections (44, 68, 94, 100) where adjacent tower sections are securely connected with a flange connection (92).
