Gases from deep sour wells in the oil industry contain appreciable amounts of hydrogen sulfide which can cause failure of many materials of construction. Stress-corrosion cracking can occur with high-strength steels and general corrosion, crevice attack, and pitting are also a problem.
Titanium is known generally to have good resistance to hydrogen sulfide containing atmospheres, but little information is available at the temperatures encountered in sour gas wells. Thus, work has been carried out with stressed titanium specimens in hydrogen sulfide and carbon dioxide mixtures at up to 220°C. After test the specimens have been examined for evidence of hydrogen pickup, weight loss, stress corrosion cracking, and reduction in mechanical properties.
The paper details the results of this work.
