Polymer Linings For Restoration And Corrosion Protection Of Steel Surfaces
By Sauereisen, Inc.
When Marsden Point Oil Refinery in New Zealand needed to reline three steel crude oil storage tanks, the engineers began a search for a lining with the necessary properties to provide a long-term solution. The existing liners had failed in many areas, allowing severe corrosion of the carbon steel tanker. Magnetic Flux Leakage (MFL) scans of the steel showed a significant loss of steel thickness due to corrosion, in some areas greater than 25%. The internal linings that had been previously installed ranged in age from 12 to 15 years old and had failed over the entire floor area and more than 3 feet up the sidewall. The selected coating for the reline of these three tanks, which totaled 54,488 square feet, was a novolak epoxy, reinforced with discrete fibers and other selected corrosion-resistant fillers and reinforcing materials.
