Abstract

The cast cover is inserted into a container in such a way that the work of deformation offsets forces within the system. The cover consists of the cover proper with prestressed ring elements providing support, a sealing flange and a "spider" for holding the arrangement in position. Large diameter tanks with or without concrete cladding and having high internal pressure and temperature may be sealed by this cover.
