Design temperature of large storage tanks and operating temperature of steel materials
Thread Content
I would like to ask the experts: Textbooks on large storage tanks, as well as various standards such as API650, GB50341, and SH3046-92, specify that the design temperature for storage tanks is 250 degrees Celsius. How is this temperature determined? And where did it come from? The operating temperatures just now varied; for example, carbon steel and low-alloy steel are generally used at temperatures ranging from 300 to 425 degrees Celsius. Is this because the material’s creep limit and endurance strength were taken into consideration? Were other factors also taken into consideration?
It might be an impact test on steel at 250 degrees.
