Abstract

The invention relates to a method for producing a connection flange. The aim of the invention is to create a method which allows the production of an annular connection flange, especially a connection flange described in DE 10 1 26 049, to be improved and simplified. Said aim is achieved by a method for producing an annular connection flange (L-flange), according to which the annular flange is carved out of a ring-shaped element that has an essentiall y triangular cross-section (profile).

Claims (3)

1. A method for the production of an annular connection flange (L-flange), wherein the annular flange is produced from an element in the form of a circular ring and the element in the form of a circular ring is of a substantially triangular configuration in cross-section (profile).
2. A method according to claim 1 characterised in that the triangular profile is cut off or shortened at one and preferably two of the three corners.
3. An annular connection flange having a tubular portion for mounting to an end of a tubular component, in particular for a pylon segment for constructing a pylon of a wind power installation, and a flange collar radially adjoining an end of the portion, with a flange surface which is oriented axially away from the tubular portion, wherein the flange collar radially inwardly adjoins a tubular portion of the connection flange and the flange collar is of a smaller thickness at the free end than in the region where the flange collar is connected to the tubular portion.
