At Oil & Gas Corrosion we frequently receive this question “If a product doesn’t meet NACE MR0175, how long will it take before it fails?”, our answer to this is always the same.

We need to assume that it will be an immediate catastrophic failure. Furthermore, you must remember that H2S is fatal in very low concentrations, therefore an uncontrolled release can lead to sudden death of anyone in range. Read more about the dangers of H2S in this article

If you allow material and equipment that does not meet NACE MR0175 / ISO 15156 to be in contact with H2S, you could be breaking the law according to the United States Code of Federal Regulations, in the United Kingdom the Health and Safety Executive regulations and local legislation in other countries. 


With a wealth of experience in the oil and gas industry, we provide independent materials and corrosion consultancy to help companies reduce risk, save money and apply best practice in their oil and gas businesses.
