When using CRA or chrome tubulars, a key concern is whether centralizers might accelerate corrosion. In fact, the opposite is true: in most cases, the centralizer (typically made from a less noble steel) will corrode first, acting as a sacrificial anode and offering protection to the more corrosion-resistant tubular.
When investing in Corrosion-Resistant Alloy (CRA) casing—especially high-chromium stainless steels—operators rightly expect long-term performance in corrosive environments. But what happens when you introduce another metal into the system—like a steel centralizer? A common misconception is that this pairing increases corrosion risk to the tubular. In reality, the opposite is typically true.
