Steel pipe materials for API Std 650 self-anchored storage tanks

The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API Std 650 self-anchored storage tanks External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.

refrigerated tanks secondary components are those whose failure would not result in leakage of the liquid being stored. Secondary components also include those API Std 650 self-anchored storage tanks components that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature vapors and have a combined tensile and primary bending stress under design conditions that does not exceed 6000 lbf/in.2. Secondary components that could be designed within this reduced stress are roof plates, including roof manways and nozzles with their reinforcement, roof-supporting structural members, and shell stiffeners.

Usually, the wind load in the API Std 650 self-anchored storage tanks construction area should be considered before the tank design and construction. The wind load in the API Std 650 self-anchored storage tanks construction area has an impact on the stability and economy of the API Std 650 self-anchored storage tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API Std 650 self-anchored storage tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

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).

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
