EN S355 plates API 650 unanchored tanks

API 650 petroleum storage tank body design is mainly the design of tank bottom, API 650 unanchored tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API 650 unanchored tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.

During the use of API 650 unanchored tanks, the tank material is prone to crack and leakage under the action of pressure, corrosion, wear and other conditions. Especially in the oil producing area, the temperature difference in four seasons is large and the natural environment is bad, which will accelerate the consumption of oil storage tank and cause many potential safety hazards. Therefore, the API 650 unanchored tanks must undergo strict inspections before being put into use after the production and installation are completed, so as to avoid cracks and leakage in short-term use and affect production safety.

Low-pressure Storage Tanks Fireproofing
Although general fire prevention and fire protection measures are expected to be fully covered by other safety codes, tanks API 650 unanchored tanks constructed according to these rules, which may be subject to fire exposure resulting from any cause, shall have their supports suitably fireproofed.
Special consideration shall be given to provisions for ample drainage facilities for accidental spills or leakage of flammable contents from such tanks or adjacent piping and other equipment if the contents may become ignited.
Subject to special considerations in isolated locations, tanks in which flammable liquid products are stored at temperatures well above their average boiling point shall be suitably fireproofed or otherwise protected.
