  • Influence of alloy elements and investigations into the behaviour of experimental low-alloy steels under practical conditions of use in seawater - CO(2) systems

Abstract

At the present time the steel industry has little interest in producing low-alloy steels resistant to seawater corrosion because of the small size of the potential market, which would appear to be restricted to uses in ports and quays (buoys, facings, jetties and pipe-piling) as well as external containment structures (sheet-piling). So far there appear to be no specific uses in offshore structures where consumption could be such as to induce the steel industry to develop production of these materials rapidly. The research reported here tackled the problem of the use of such steels in components of offshore structures which come into contact with highly corrosive systems, for instance CO(2)-seawater mixtures, typical of many offshore oil and gas deposits. The intention was to check whether low or medium levels of alloying with elements such as Cr, Mo and Al are capable of increasing the corrosion resistance of steel in seawater-CO(2) systems, so as to provide the steel industry with useful guidelines for the development of tubular goods for the production and transmission of oil and gas in the presence of such systems.
