API 650 low-alloy steel tanks anchored with mechanical devices

When the day light gradually decreases, the temperature of oil in the API 650 low-alloy steel tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API 650 low-alloy steel tanks will also decrease. When the pressure in the API 650 low-alloy steel tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API 650 low-alloy steel tanks through the open vacuum valve, which is the "suction" process of the oil tank.Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API 650 low-alloy steel tanks material specimens shall be of sufficient length to locate the notch in the heat-affected zone after etching. The notch shall be cut approximately normal to the material surface to include as much heat-affected zone material as possible in the resulting fracture. Impact test specimens shall be cooled to the temperature stated in Q.22.Welded steel API 650 low-alloy steel tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API 650 low-alloy steel tanks all adopt on-site production and installation of storage tanks.The company's quality is first, the price is reasonable, the construction period is guaranteed, and the purpose of abiding by the contract, our steel API 650 low-alloy steel tanks products have received high recognition from customers from the world.
