  • Clad linepipe overcomes corrosion losses

    Martin Connelly

    Traditional carbon steel linepipes made of High-Strength, Low-Alloy (HSLA) steels exhibit corrosion rates of approximately 0.2 mm/yr under environmental conditions such as 10 bar of CO2 at 60°C, whereas Corrosion Resistant Alloy (CRA) materials exhibit 0.005 mm/yr or less under the same conditions. This means, given a 30-yr pipeline lifetime, that a 6-mm wall thickness loss would occur for HSLA steel, whereas CRA would lose less than 0.15 mm.
