12m diameter API standard 650 flat-bottom steel tanks
The floating roof is the top cover floating on the liquid level, so the sealing performance of API standard 650 flat-bottom steel tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API standard 650 flat-bottom steel tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.
As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.
The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.
Shell Stiffening Rings for Tanks That Contain LiquidInternal or external shell stiffening rings may be required to maintain roundness when the tank is subjected to wind, vacuum, or other specified loads. When API standard 650 flat-bottom steel tanks stiffening rings are required, the stiffener-to-shell weld details shall be in accordance with Figure Q-1 and Q.3.5.2 through Q.3.5.5.Three-plate laps or butt-weld junctions in tank bottoms shall be not closer than 12 in. from each other or from the butt-welds of the annular plates.Bottom plates, other than annular bottom plates for a 9% or 5% nickel steel or stainless steel tank that contains liquid, may have a minimum thickness of 3/16 in. exclusive of any specified corrosion allowance.
