Abstract
A tubular apparatus, particularly a steam generator, in which U-shaped or straight tubes are inserted in the casing. A series of gratings are provided in the casing and comprise parallel grating elements made up of grating bars and cross-bars formed to firmly hold the tubes in place and separate them from one another. Facilitation of inserting the tubes in the casing is accomplished by emplacing grating elements corresponding to grating elements in other gratings first and continuing in a like manner.
