PRESSURE CONTAINER FOR HOT FLUIDS

摘要

A high temperature pressure vessel has a metal wall with an inner layer and a number of plies laid round it and intermediate spaces filled with a solid heat-insulating medium such as asbestos. The spaces occupy, at least in the hottest region of the vessel, more than one fifteenth and preferably at least one tenth to one half of the volume of the wall. In the region of the intermediate spaces, the inner layer is separated from the outer plies by pressure transmitting ribs.
