| Popis: | The resistance of steel of strength group K to corrosion, hydrogen-corrosion, and stress-corrosion fracture is analyzed for hydrogen-sulfide-containing media of the Lokachi gas field and in the NACE solution. It is shown that the indicated type of steel is not susceptible to hydrogen-induced cracking, its resistance to sulfide fracture σ ssc ≈ 0.8 σ0.2 min, and the rate of corrosion is much lower than the dangerous threshold value. This enables us to conclude that the tubing and casing strings made of this type of steel can be safely exploited at the Lokachi gas field. |
