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.

CC Technologies provides a full range of corrosion testing services to help minimize the corrosion related problems, and to qualify materials in sour gas production, gas treating plants, and petroleum refineries.

Capabilities include many ASTM Standard and NACE Recommended Test Methods, including:

CC Technologies has set up a dedicated H₂S laboratory in its new facilities. This laboratory is designed to provide state-of-the-art H₂S testing capabilities, while providing for the safe and efficient handling of H₂S.

Custom designed facilities for testing in H₂S environments are also available. CC Technologies can perform tests in high-temperature and pressure H₂S environments requiring alloy C-276 autoclaves. Various sizes of autoclaves are available for testing, and a variety of tests can be performed in H₂S environments. These include Slow Strain Rate (SSR), constant load, corrosion fatigue, and fracture mechanics testing. Electrochemical tests that can be performed at high temperature and pressure include potentiodynamic polarization, polarization resistance, and electrochemical impedance spectroscopy. Such tests have been used to evaluate inhibitor efficiencies and pitting characteristics of alloys.

In addition to aqueous tests, test facilities are available to evaluate material performance in high-temperature gas environments. These tests have included stress rupture tests in hydrogen/H₂S environments.

Our clients for H₂S testing include alloy producers, manufacturers of tubular and welded products, gas pipeline companies, oil and gas producers, turbine and compressor manufacturers, plant operators, and refineries.
