Steam generator pipe, associated production method and continuous steam generator

摘要

Steam generator pipe (10) has an insert (22) which is arranged in the inner chamber of the pipe (18) in order to form a swirl-generating inner profile. The insert comprises a lamination frame (24) having a number of large recesses (26). The insert is drilled in the longitudinal direction and rests partially on the pipe inner wall (36) with the longitudinal edges (30). An independent claim is also included for the method for the production.
