API 650 partially anchored liquid-storage tanks subject to a small internal pressure

The API 650 is the American standard for welded flat-bottomed vertical API 650 partially anchored liquid-storage tanks storage tanks. This standard dictates tank design, manufacture, welding, inspection and installation requirements.

The heat transfer oil fin tube heating device for large API 650 partially anchored liquid-storage tanks heats the circulating heat transfer oil in the shell and tube heat exchanger through high temperature and high pressure steam. The heat transfer oil exchanges heat with the medium to be heated in the storage tank through the heating coil, so as to heat the storage medium. High temperature heat transfer oil fin tube heating device has the following advantages:
1. High heat transfer efficiency
2. Reduce heating coil leakage
3. Easy to repair and maintain

API 620 Tank Design
The designer of these large tanks API 650 partially anchored liquid-storage tanks shall supply the data on superimposed loadings to be assumed for the foundation design or, if there are no foundations, for direct loading on the subgrade. A slab or mat may be provided to support the superstructure and shall be considered to distribute the load more evenly over a lower natural subgrade compared with merely stripping, leveling, and rolling the existing grade.
For simple spheroids or tanks of similar design, in which the distribution of the imposed weights shifts because the liquid level in combination with the vapor pressure may change the shape of the tank, the designer shall consider the possibility of such a change.

As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.

Box making, door-to-door: fill in the packing plan: box making time, ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, door point, contact person, telephone number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date). Internal loading: fill in the packing plan: ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, cabin number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date).
