API Std 650 open-top tanks secondary seal
API 650 petroleum storage tank specifications and standards are documents verified by the customer (owner) under different operating conditions; however, API Std 650 open-top tanks it must be verified whether these API 650 petroleum storage tank documents are suitable for use and whether they comply with applicable design specifications and/or specifications.
Allowable Design StressesThe maximum allowable design stresses for the API Std 650 open-top tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.
Usually, the wind load in the API Std 650 open-top tanks construction area should be considered before the tank design and construction. The wind load in the API Std 650 open-top tanks construction area has an impact on the stability and economy of the API Std 650 open-top 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 open-top 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 after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
