The construction of foundations for API standard 650 self-anchored flat-bottom tanks
The safety inspection of atmospheric storage tank, API standard 650 self-anchored flat-bottom tanks is divided into external inspection, internal and external inspection and comprehensive inspection. External inspection shall be conducted at least once a year, internal and external inspection shall be conducted at least once every three years, and comprehensive inspection shall be conducted at least once every six years. The safety inspection of large atmospheric storage tanks, API standard 650 self-anchored flat-bottom tanks requires special attention: the parts where the liquid level often fluctuates, the parts that are susceptible to corrosion, and the parts that are deformed and worn during use should be checked.
Impact Requirements for Controlled-rolled or Thermo-mechanical Control Process (TMCP) Plates: Subject to the approval of the Purchaser, controlled-rolled or TMCP plates (material produced by a mechanical- thermal rolling process designed to enhance the notch toughness) may be used where normalized plates are required. API 620 welded storage tanks each used plate, as rolled, shall be Charpy V-notch tested to the requirements of R.2.1.2.
The effect of air pressure on the API standard 650 self-anchored flat-bottom tanks tank walls of the API 650 tank must be considered when the design pressure is greater than 2 kPa.The fixed point method can be used to design the tank wall of atmospheric or micro internal pressure API standard 650 self-anchored flat-bottom tanks storage tank.
