NACE MR0175

NACE International (now AMPP) standard for materials for use in H2S-containing (sour) oil and gas environments, to prevent sulfide stress cracking (SSC). Specifies maximum hardness limits for carbon steel (22 HRC max), low-alloy steel, and CRA materials. Equivalent ISO standard: ISO 15156.

Frequently Asked Questions

What does NACE MR0175 cover?

NACE International (now AMPP) standard for materials for use in H2S-containing (sour) oil and gas environments, to prevent sulfide stress cracking (SSC). Specifies maximum hardness limits for carbon steel (22 HRC max), low-alloy steel, and CRA materials. Equivalent ISO standard: ISO 15156.

Which valves require compliance with NACE MR0175?

NACE MR0175 compliance is typically required for valves used in oil & gas, petrochemical, and industrial process applications where the standard applies. Procurement specifications for EPC projects and operating companies often mandate specific standards as part of the Material Requisition (MR). Vajra Industrial Solutions supplies valves with full certification documentation including NACE MR0175-compliant test certificates.

Does Vajra Industrial Solutions supply NACE MR0175-compliant valves?

Yes. Vajra Industrial Solutions supplies industrial valves with third-party inspection and full documentation packages including material test certificates (MTC/EN 10204 3.1), hydrostatic test reports to the applicable standard, and dimensional inspection records.
