Abstract
This paper discusses corrosion problems in the Petrochemical Industry associated with the use of Thermal Insulation. Actual case his tories are presented which illustrate the difficulties in avoiding corrosion when insulating outdoor equipment such as towers, drums and piping.
The serious consequences to critical equipment resulting from inatten tion to minor design and construction techniques are illustrated in the case of towers. Practical corrective and preventive procedures which have been developed as a result are described.
In addition, a method developed to reduce corrosion of outdoor insula ted piping supported from hanger rods is illustrated.
Finally, a method used to re-insulate large refrigeration drums operating in the -30°F (-34°C) range while remaining in continuous operation is described.
