API 650 welded steel storage tanks impulsive natural period

Proper use of API 650 welded steel storage tanks and precautions:
1. The API 650 welded steel storage tanks must be used within the safe height range;
2. Check before use to ensure that the safety valve and breathing valve are flexible and easy to use;
3. The explosion-proof and fire-proof safety measures for oil tanks are implemented effectively;
4. The oil level in the API 650 welded steel storage tanks should be accurately measured when receiving and delivering oil, so as to prevent overflow or empty;
5. In the process of receiving and sending oil, the flow rate of oil should be controlled, and it should not be too fast to avoid electrostatic accidents.Test plates shall be welded using the same qualified welding procedure and electrodes that are required for the tank shell plate joints. The API 620 steel storage tank test plates need not be welded as an extension of the tank shell joint but shall be welded in the required qualifying positions. One test weld shall be made on a set of plates from each specification and grade of API 650 welded steel storage tanks plate material, using a thickness that would qualify for all thicknesses in the shell. Each test welded of thickness t shall qualify for plate thicknesses from 2t down to t/2, but not less than 5/8 in. For plate thicknesses less than 5/8 in., a test weld shall be made for the thinnest shell plate to be welded; this test weld will qualify plate thicknesses from t up to 2t.For open top and fixed roof API 650 tanks, the net working capacity is the liquid volume contained between the minimum operating level (top of API 650 tanks API 650 welded steel storage tanks outlet connection) and the maximum operating level [limited to the bottom of overflow connection, 75 mm below foam chamber connection, or 150 mm below rim, whichever is greater.The company has always been adhering to the business philosophy of "integrity-based, responsibility oriented, quality first, reputation first" and is committed to building a world-class steel materials and service provider.
