N2 - The manufacturing technology of corrosion resistant alloy (CRA) clad UOE pipe for pipelines transporting oil and gas containing H2S, CO2 and other chemicals has been studied. The required corrosion resistance of the CRA layer was achieved in the as-rolled condition by optimizing the thermomechanical control process (TMCP) conditions for manufacturing the clad plate. In order to obtain good corrosion resistance in the CRA layer, it is necessary to ensure complete recrystallization and suppress the precipitation of chromium carbides in the CRA layer after rolling. To this end the clad plate was finish-rolled at high temperature and water-cooled after air cooling. However, in conventional steel high temperature rolling causes a considerable deterioration in the low-temperature toughness, therefore, a low C-high Nb-Ti microalloyed steel, which exhibits a fine-grained microstructure even under high temperature rolling, was developed for the base material of CRA clad UOE pipe.
