摘要
High-strength pipes are manufactured from cold-deformed carbon steel or alloyed steel for use in acid environment, in which the H2S partial pressure in gaseous phase may exceed 300 Pa or in which the H2S content in liquid phase may have a corresponding equilibrium pressure and/or in which CO2 and other acidifying substances may be present. The weight % composition of the steel is preferably: C 0-1.20% Si 0-1.0% Mn 0-3.0% Cr 0-2.0% Ni 0-1.0% Mo 0-1.0% Cu 0-1.0% V 0-0.3% Nb 0-0.2% Ca 0-0.05% Fe+incidental ingredients and impurities up to 100%.
