THERMAL INSULATION
Equipment or pipe work with an operating temperature greater than 55°C in case of metallic surfaces and 65°C in the case of non-metallic surfaces should be insulated so that the surface temperature after insulation (cold surface temperature) does not exceed 55°C. It is recognized that temperatures of 60°C or greater will result in extreme discomfort to personnel and therefore a maximum cold surface temperature of 55°C should be considered as prudent. Typical products to be used for applications are calcium Silicate, Ceramic Fibre Blanket, Glass Wool, Perlite, Stone Wool, Rock Wool.
