CRA Nace: Requirements for Corrosion-Resistant Claddings and Linings

NACE MR0175 is an international standard that outlines the requirements for metallic materials exposed to H₂S in oil and gas production environments. The standard provides guidelines for corrosion-resistant claddings and linings, including chemistry, heat treatment condition, microstructure, corrosion testing, welding requirements for overlay weld deposition, and dilution requirements, among others.

Why Compliance with NACE MR0175 is Important

It is crucial for materials used in upstream hydrocarbon production that are cladded or lined with CRA and exposed to H₂S to comply with NACE MR0175. Failure to meet the requirements or to use base materials that are susceptible to H₂S related damage mechanisms can result in catastrophic equipment failure, leading to H₂S release into the environment.
