API 650 floating-roof tanks convective (sloshing) period

Standard API 650 tank calls for calculations based on the specific gravity of the liquid product being stored. This permits the thickness of the steel API 650 floating-roof tanks needed as well as other specifications of how the tank is built to be determined by the weight of the API 650 tank.

Structural shapes of 9% and 5% nickel steel may be furnished to the chemical and physical requirements of ASTM A353, A553, or A645. Physical tests shall be in accordance with the requirements of ASTM A6.
API 650 floating-roof tanks used Piping, Tubing, and Forgings
Material used for piping, tubing, and forgings shall be compatible in welding strength, and thermal expansion coefficient with the tank shell material. In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.

Personnel organization before the construction of the API 650 floating-roof tanks:
The company shall select technical personnel, quality inspectors and material personnel with organizational ability and construction management experience to participate in the API 650 floating-roof tanks project construction. The construction personnel shall arrive at the construction site before the designated commencement date, investigate the construction site, build construction facilities, plan the construction steps, and analyze the potential safety hazards during operation.
