Problem: A well known crisp manufacturer had a series of aging gas pipes of diameters ranging between 4 to 8 inch. These heavily corroded pipes were located in the ceilings above production equipment and the packing conveyors. In addition, because of the processes in the rooms beneath, the roof area had excessive heat and humidity, with water condensate perpetually laying on the pipes. Grit blasting was not an option due to production beneath and so Belzona was approached to offer an anti-corrosion system that could be applied in such difficult circumstances.
