Design is first step in all life cycle of pipeline system, so it is important that integrality idea is considered adequately at design period. Corrosion will be more badly with more long time at operating period. Corrosion is one of key threat to pipeline system integrality in H S/CO gas field. This paper introduced material selection process, corrosion risk assessment 2 2 method and corrosion control framework. Those consider may provide a reference for pipeline system design based on corrosion risk. Key word: Corrosion risk, Integrality, Design, H S/CO
