What is “sour service” and do Hackney Ladish, Inc. fittings comply?
Sour service is generally defined as service involving hydrogen sulfide bearing hydrocarbon fluids of varying concentrations. This service presents special problems relating to sulfide stress cracking (SSC). In order to maximize resistance to SSC, the oilfield industry and NACE developed the standard MR0175 for Sulfide Stress Cracking Resistant Metallic Materials for Oilfield Equipment. All Hackney Ladish, Inc. fittings comply with requirements of MR0175 and can be used in nearly all-sour service applications. If severe service applications require additional precautions beyond MR0175, we can supply those fittings on request.
