NACE SP0592-2022, Application of a Coating System to Interior Surfaces of New and Used Rail Tank Cars in Concentrated (90 to 98%) Sulfuric Acid Service

Product Number: NACE SP0592-2022
Publication Date: 2022
$109.00

A large number of commercial 93 to 98% sulfuric acid (H2SO4) shipments in the United States and Canada are transported by rail in carbon steel tank cars. Concentrated sulfuric acid (93-98%) is an oxidizing agent and a desiccant. The major problems in its handling and storage relate to its hygroscopic nature (absorption of atmospheric humidity), its exothermic reactivity with water on dilution, and velocity effects that erode the otherwise protective films of corrosion products.

This standard is intended for use by tank car owners, coating systems suppliers, and coating system applicators for the auditing of the facilities, equipment, and personnel that satisfy the requirements for tank car coating systems in sulfuric acid service.
