Multilayer high pressure cylindrical vessel APT in particular for high pressure processing

Abstract

A multilayer high pressure cylindrical vessel (1) has an inner metal cylinder (3), the inner surface defining an inner volume of the vessel (1) along the radial direction, an outer metal cylinder (4), and one intermediate cylindrical layer sandwiched in space between the inner cylinder (3) and the outer cylinder (4) has and comprising a number of circular wedge segments (51) separated by gaps (52). To improve the vessel there exists an interference fit between the one intermediate cylindrical layer and the adjoining solid cylinders and said gaps (52) are broken by bridges (522) connecting angularly adjacent circular segments (51) and defining two axially adjacent gap sections (521) so that the cylindrical layer is a single cylindrical element (5), and the circular wedge segments (51) separated by gaps (52) both extend in parallel to each other along the longitudinal axis of the vessel (1).
