Device for the manufacture of hollow bodies of self-entangling or overpressed steel with permanent deformation of the wall by application of an internal pressure consisting of a hydraulic press whose plates are arranged so as to seal the two ends of the hollow body in which at least one of the plates comprises the admission of the fluid under pressure characterized in that at least one day the ends of the hollow body have a sliding joint between said end and the plate of the press. Which automatically compensates for the shrinkage that results from the expansion of the wall. (Machine-translation by Google Translate, not legally binding)
