API standard 650 cylindrical liquid-storage tank wax scrapers
API 650 "welded storage tanks" API standard 650 cylindrical liquid-storage tank is a standard developed and issued by the American Petroleum Institute (API), which specifies the minimum requirements for the design, manufacture, installation and inspection of welded storage tanks.
Natural ventilation loss: the main cause of natural ventilation loss is that the API standard 650 cylindrical liquid-storage tank 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 cylindrical liquid-storage tank 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.
Stamping of API 620 Storage Tank PlatesBefore plates required to be stamped by the steel mill are used, the inspector shall see that they bear the stamp. In laying out and cutting the API standard 650 cylindrical liquid-storage tank plates, at least one set of the original material identification markings should, if possible, be left where it will be plainly visible when the tank is completed. Should the identifying marks be obliterateSpot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.
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.
