An annular flange (5, 6) to be welded to a tubular segment of a power pylon has an end face (15) to face an end face (15) of an opposing flange (5, 6). The annular flange (5, 6) has through bores (9) distributed in a circle. The end face (15) has a central annular recessed zone (16) that is machined in said end face (15). The central annular recessed zone (16) is flanked by a radially outward engagement surface (17) and a radially inward engagement surface (18) which form the interface with the opposing flange (5, 6).
