ABSTRACT:
A process for producing a detachable insulation for inaccessible hollow spaces on warm installations of pipelines, fittings, and containers includes the steps of surrounding the installation with a sheet metal jacket, supporting the sheet metal jacket at a spaced location from the installation in order to form a hollow space between the sheet metal jacket and the installation, filling the hollow space through an opening in the sheet metal jacket with free-flowing insulating material and a binder, curing the binder to form a rigid insulating shell, removing the sheet metal jacket, and cutting the insulating shell by appropriate axial and radial cuts to form individually removable insulation sections.
