Research And Analysis On Installation Construction Of 100,000 M~3 Steel Vertical Tank

Throught the study of general design proposal and construction process of 100,000 m³ steel vertical tank in Dalian Petroleum Reserve Base, The paper analyzed the fixed form of soleplate and rails tie plate used in the bottom of tank ,in order to ensure the planeness, CO₂welding and scientific welding approach were strongly recommended ; and to make sure one-time molding for tank wall assembly ,reasonable proposals needed to make decision.by means of choosing optimized tank wall groove style, warm-up scheme, welding programmer and polishing & cleansing proof measures, the one-time qualified rate of welding can reach 98%; on the basis of research on the chemical ,strength character,welding performance of Japanese SPV 490 and Chinese 12MnNiVR , and combining with the usage of domestic high strength board 12MnNiVR , the domestic high strength board was choosed , which come ture the percentage of home made parts on core material in Dalian Petroleum Reserve Base; aimed at the prevent and settlement of the problems which may happen in the process of construction and production ,a lot of optimization measures were proposed , which provided reliable references for tank construction in the future.
