Dissimilar Metals

The oil and gas industry often uses chromium piping (also referred to as corrosion resistant alloy tubing or CRA tubing) in wells that extract oil or gas. This piping is susceptible to dissimilar metal corrosion, meaning that it oxidizes or corrodes simply by being in contact with another metal such as steel. At a price tag of $40,000-$60,000 per pipe, this is a big problem.
