<p>The storage and/or service vessel is for liquid and/or gaseous commodities and/or material in bulk, having latticework walls of high rigidity clad internally with corrosion-resistant material also forming the bottom. The vessel has, along the sidewalls (2) at least, an airtight outerwall (20) resting on the latticework(4). Either the internal cladding (5) or the outer wall has one or more ports, connected to a vacuum source. This port can be closed by a non-return valve, opening towards the source, and to the other side of which an exhauster is connected.</p> |
