介绍 | Sanicro 29 is a high-alloy austenitic stainless steel (CRA) for OCTG downhole applications in particularly corrosive conditions. The grade is characterized by:
Sanicro 29 is developed specifically for improved localized corrosion resistance where the environment contains high chloride concentrations, CO and H S at high temperatures. Such an environment causes corrosion in lower alloyed materials. Sanicro 29 offers a cost effective solution to such corrosion problems over the more expensive nickel alloys. Applications Sanicro 29 is used for high strength downhole production tubing, casing, and liners in sour gas wells. This includes environments with high temperatures, high partial pressures of CO2 and H2S, and high chloride concentrations. |
