ASTM A283 plates API standard 650 open top welded storage tanks

API 650 is the standard for welded tanks for oil storage. It specifies the API standard 650 open top welded storage tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.

In this project, an area of steel storage oil tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 6000 lbf/in.2.

Proper use of API standard 650 open top welded storage tanks and precautions:
1. The API standard 650 open top welded 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 standard 650 open top welded 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.
