Liquid Storage & Handling

NASi anti-icing/de-icing products are formulated with a proprietary corrosion inhibitor package to improve its compatibility with copper, brass, aluminum, aluminum alloys, zinc, and other metals and alloys. The corrosion inhibitors work by forming a protective barrier between the metal and the liquid runway de-icing products (LRD). All equipment surfaces that are frequently exposed to de-icing products should be routinely rinsed with warm water (especially before and after the winter season) to prevent the accumulation of residue, minimize staining, and maintain equipment integrity. 

Pumps

The preferred material is stainless steel; however, plastic is acceptable. While the corrosion inhibitor package improves compatibility with brass, cast aluminum, and cast iron, these materials should be avoided because of abrasion effects. Avoid pumps that contain zinc or galvanized wetted parts. The high abrasion effects combined with the reactivity of LRD towards zinc will dissolve the galvanized coating.

Pipes

Acceptable materials are stainless and carbon steel, polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), butyl and natural rubber. Minimize contact with zinc or galvanized metals. While welded or flanged pipe joints are recommended, threaded fittings and joints are acceptable when a high quality pipe sealant is applied. 

Seals and Gaskets: Recommended materials are natural and butyl rubber, ethylene propylene rubber (EPR, EPM, EPDM) and isoprene. Neoprene and nitrile (Buna-N) rubbers are acceptable. Materials to avoid are: any type of silicon rubber, styrene butadiene (Buna-S), polyurethane, polyacrylate, fluorosilicone and fluorocarbon rubbers and butadiene.

Tanks

Stainless steel, fiberglass or polyethylene tanks are recommended. If clean and rust-free, alloy steel or carbon steel tanks may be used. While acceptable in the presence of the corrosion inhibitor package, aluminum tanks should be avoided for long term storage. Ensure tanks are designed to accommodate the viscosity, relatively high density, and low surface tension of LRD’s. Containment should be compliant with local regulatory requirements. Prior to fill, inspect tanks to ensure they are free of residue, rust, or other particulates.
