material selection strategy for corrosion control in iranian upstream oil and gas industry

Material selection process is one of key stages in integration assurance of the system. some important parameters in selecting suitable materials for using in a specific working and environmental condition include: design pressure and temperature, weldability, costs and corrosion concerns. nowadays, the last one attracted attentions of the both researchers and owners. codes like iso 21457 necessitate providing material selection procedure report before proceeding next steps of the project. without any specific material selection procedure; the material selection process will be a complex and confusing task because of the diversity in codes and fluid service conditions. the aim of this study is to introduce researchers and engineering with corrosion concerns especially in co2, h2s and salt contained services and the solutions which are normally employed in iranian upstream oil industry to tackle with these problems. towards, environmental deterioration problems in iranian oil and gas fields are discussed and the related treatments are presented.
