32-Inch CRA-Lined Pipes: Advancing Performance for Offshore & CCUS Applications

By Cladtek Holdings Pte Ltd
Corrosion-resistant alloy (CRA) materials play a pivotal role in submarine pipelines, addressing internal corrosion caused by transported fluids. In environments where carbon steel is insufficient due to technical, operational, or economic challenges, CRAs provide a reliable alternative. Corrosion risks are particularly significant in the presence of carbonic acid (formed from dissolved CO₂) and hydrogen sulfide (H₂S), which create complex material selection scenarios and effective solutions. The study evaluates critical performance metrics, including wrinkling thresholds during bending and hydrotesting effectiveness. Results affirm the suitability of 32-inch CRA-lined pipes for offshore and subsea applications, including carbon capture, utilisation, and storage (CCUS), further solidifying their role as a transformative solution for modern pipeline infrastructure.
