Pipe insulation for horizontal runs - comprises trapezoidal shell with dividing cut for subsequent pipe insertion

摘要

The insulating shell (1) has a trapezoidal section, the tube to be inserted in the shell eccentric to the smaller side face of the two parallel side faces (12,13). The shell can be divided by a cut extending from the smaller side (13) to the large (12) so the pipe can be inserted subsequently. The shell is typically made from polyurethane foam or cut out of foam or elastomer. The shell can also be strengthened over its surface by a hot-melt glued film or foil, using film etc. also to close up the cut after tube insertion where used.
