    Abstract - (Show below) - (Hide below)

    Describes aspects of thermal insulation of pipework and equipment in the temperature range - 100 degree C +870 degree C. May be found suitable for the insulation of road and rail transport vehicles and of some assistance in marine insulation. Covers definitions, exchange of design data, factors effecting planning and programming, selection of insulating materials and systems, site considerations, methods of application, finishes and their methods of application, inspection, testing and maintenance, guarantees, design considerations, tables and figures.
