Large API standard 650 ground supported flat-bottom 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 ground supported flat-bottom tanks tank wall thickness is not considered in the tank wall design.

Natural ventilation loss: the main cause of natural ventilation loss is that the API standard 650 ground supported flat-bottom tanks is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API standard 650 ground supported flat-bottom tanks is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.

Materials for API standard 650 ground supported flat-bottom tanks primary components shall comply with the requirements of Tables R-1 and R-2. All primary components shall be impact tested in accordance with R.2.1.2 through R.2.1.4. Impact testing of API 620 welded storage tanks plates, including structural members made of plate, shall comply with Table R-1. Impact test specimens shall be taken transverse to the direction of final plate rolling.

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, API standard 650 ground supported flat-bottom tanks and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
