<p>The utilization of thermally insulated bodies is function, on one hand, of their insulating power and, on the other hand, of their manufacturing cost. A particularly simple process allows to manufacture a thermally insulated body, for example a pipe with an inner, preferably metal wall (20), and an outer, preferably metal wall (21), wherein the space (22) formed between said two walls is vacuum sealed, is under vacuum conditions and is filled with a porous, particulate and/or powdery insulating material (6). This process consists in creating a vacuum in the space (22) between the inner wall (20) and the outer wall (21), whereafter the insulating material (6) is introduced from a depression chamber (1) into the depression space (22) which is then sealed. </p> |
