Behavior of API standard 650 aboveground steel oil storage tanks
When API 650 storage tank is designed, when the design pressure is small F2 kPa, the impact of air pressure on the API standard 650 aboveground steel oil storage tanks tank wall thickness is not considered in the tank wall design.
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).
All welded seams in the API standard 650 aboveground steel oil storage tanks bottom, and complete penetration and complete fusion sidewall-to-bottom welds, shall be inspected by means of a vacuum box test as described in Q.8.2.1. Sidewall-to-bottom welds not having complete penetration and complete fusion shall be inspected by means of either a vacuum box test of the inside weld as described in API 620 specification Q.8.2.1, or where approved by the Purchaser, a direct pressure solution film test as described in Q.8.2.2.
The cost of mechanical cleaning for vertical storage tank, API standard 650 aboveground steel oil storage tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API standard 650 aboveground steel oil storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API standard 650 aboveground steel oil storage tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.
