| Abstract: | To satisfy the requirement for oil/gas transport under acidic operation conditions, the L245NCS steel is produced with its chemical composition well designed. With all the operation steps, particularly the heat treatment process strictly controlled, the HIC and SSC L245NCS steel oil/gas linepipes in possession of good structural and mechanical properties are developed. Briefed in the paper are the main aspects of the said linepipe, including the chemical composition, technological design, manufacturing process as well as relevant testing/inspection results. |
