Corrosion Resistance Analysis of Super Duplex Stainless Steel in Seawater System of Offshore Platform Heat Ex-changer Skid
Based on foreign industry standards and domestic usage experience,the frequent leakage of super duplex stainless steel pipelines in the seawater system of shell and tube heat ex-changer skid on the offshore oil platform are analyzed.It is found that metallurgical status,seawater temperature,welding characteristics,and material pollution are the main causes of corrosion leakage of super duplex steel in seawater systems.Then,some methods are proposed to reduce leakage risk from the system process,metallurgy,welding,operation,etc.,and have been well applied in subsequent equipment modifications.
