Design and construction requirements for API Std 650 ground supported flat-bottom tanks

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API Std 650 ground supported flat-bottom 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.Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API Std 650 ground supported flat-bottom tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve API Std 650 ground supported flat-bottom tanks work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.Generally, the snow load in the API Std 650 ground supported flat-bottom tanks construction area should be considered before the design and construction of the tank. The snow load in the API Std 650 ground supported flat-bottom tanks construction area has an impact on the tank roof design and operation, especially in the area with large snow load, the roof load of large storage tank with large diameter increases. Anti freezing, heat preservation and waterproof measures shall be taken for the additional facilities of storage tanks, such as pumps, breathing valves, flame arresters, detection instruments and thermal insulation layers.
