API 650 welded steel storage tanks sliding resistance

Materials for API 650 welded steel storage 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.

API 650 storage tank, double-layer oil tank environmental protection advantages: ordinary single-layer steel API 650 welded steel storage tanks oil tank is corroded by underground water and gas and electrolytic corrosion because it is buried underground all year round. The API 650 tank has a double-layer structure with a gap of 0.1 mm. The API 650 welded steel storage tanks outer layer of FRP ensures that the leakage will not directly leak into the soil and water source.

High temperature heat transfer oil fin tube heating device for large API 650 welded steel storage tanks has the advantage of high heat transfer efficiency. The high-temperature heat-conducting oil finned tube heating device adopts high-efficiency outer finned tubes. The outer finned tube coils are immersed in a water bath. Compared with ordinary light tubes, the contact area between the evaporation coils and the medium is increased. The total heat transfer coefficient of the coil is determined by the heat transfer coefficient outside the tube. This increases the heat flux per unit tube length and improves the overall heat transfer efficiency.
