Is NACE MR0175 used only for sour service?

NACE MR0175 is an international standard that provides the requirements for metallic materials exposed to H2S in oil and gas production environments. NACE MR0175 is identical to ISO 15156. ANSI / NACE MR0175 / ISO 15156 lists the requirements for carbon steels, low alloys and corrosion resistant alloy exposed to H2S in oil and gas exploration and production environments.

NACE MR0175 defines sour service as “Exposure to oilfield environments that contain sufficientH2S to cause cracking of materials by the mechanisms addressed by NACE MR0175/ISO 15156”.

If your production environment is not at immediate risk of H2S exposure, then NACE MR0175 may be applicable. To get expert advice talk to our team, our experts in sour service will help you determine the requirements for your project.
