H2S Corrosion Testing DNV provides you with cost effective solutions to materials, corrosion and integrity problems. Hydrogen Sulfide (H2S) corrosion problems are increasing in severity in the oil and gas production and oil refining industries as fields age and sweet oil and gas reserves are depleted. The most severe corrosion related problems are Sulfide Stress Cracking (SSC) and Stepwise Cracking. DNV provides a full range of corrosion testing services to help minimize the corrosion-related problems and qualify materials in sour gas production, gas treating plants, and petroleum refineries. The dedicated H2S laboratory is designed to provide state-of-the-art H2S testing while ensuring safe and efficient handling of H2S.
high-pressure H2S environments requiring alloy C-276 autoclaves of various sizes, including Slow Strain Rate (SSR), constant load, corrosion fatigue, and fracture mechanics testing. High temperature and pressure electrochemical tests, such as potentiodynamic poliarization, polarization resistance, and electrochemical impedance spectroscopy, are used to evaluate inhibitor efficiencies and pitting characteristics of alloys. Facilities are available to evaluate material performance in high-temperature gas environments. These tests include stress rupture tests in hydrogen/H2S environments.
Clients in the following areas will benefit from H2S testing: • Alloy producers • Manufacturers of tubular and welded products • TM0177-90 Resistance to SSC—Proof Ring Testing • Gas pipeline companies • TM0284-87 Resistance to Stepwise Cracking—Hydrogen • Oil and gas producers Induced Cracking (HIC) • Turbine and compressor manufacturers Custom-designed facilities for testing in H2S environments are • Plant operators also available. DNV performs tests in high-temperature and • Refineries Capabilities include many ASTM Standard and NACE Recommended Test Methods, including:
