What Does Thermal Insulation Mean?
Thermal insulation is the process of insulating material from transferring heat between the materials that are in thermal contact. Thermal insulation is measured by its thermal conductivity. Low thermal-conductive materials are used for thermal insulation. Besides thermal conductivity, density and heat capacity are also important properties of insulating materials.
Corrosion under insulation is prevalent in petrochemicals and other industries where pipes and equipment are insulated from heat. Corrosion normally occurs on the insulation materials underlying piping or equipment. It also affects the insulation of jacket materials.
