Abstract
A device for mounting a conduit in an opening of a plate, especially for mounting a heat-exchanger tube in a support plate of a high-temperature heat exchanger. The tube is mounted in the opening of the support plate via the interposition of at least one sleeve-like wear-protection element, with the positioning of the tube being secured by welding. To guarantee a reliable connection between the plate and the tube that can be tested and can also be utilized at high temperatures, at least one build-up weld is provided on the tube. This build-up weld is in frictional and/or positive engagement with the inner surface of the at least two-part wear-protection element.
