Abstract

The tube wall in section across the corrugation, and correspondingly across the plate longitudinal direction, has a corrugation pattern in the form of a periodically transversal wave curve (2) with alternating valleys and peaks in an XY plane. - The X-direction is the wave curve extending direction and the Y-direction is the transversal direction in towards the tube interior. The tube wave curve within each period (T) comprises a value (3) with large amplitude (A) and a series of peaks (4) and valleys (5) with lesser amplitudes (a). - (Dwg.2/2)
