Process for producing an annular connection flange, and annular connection flange

摘要

A method for the production of an annular connection flange includes producing the annular connection flange from an element in the form of a circular ring. The element in the form of a circular ring has a substantially triangular profile. An annular flange includes a tubular portion configured to be mounted to an end of a tubular component, and a flange collar adjoining an end of the tubular portion and extending radially inwardly therefrom.
