摘要

A heat insulation system for gas conduits in which open cylinders are placed side by side coaxially within the conduit. Each cylinder has an inner and outer wall, the gap between the walls being occupied by concentric metal layers which are so shaped and stacked that a number of longitudinal gaps are provided between any two metal layers. The gap is closed either at the upstream end of the cylinder or in the central zone.
