A516 Gr 450 plates API Std 650 self-anchored tanks
API 650 is the standard for welded tanks for oil storage. It specifies the design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 API Std 650 self-anchored tanks is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI, used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API Std 650 self-anchored tanks API 650 tanks with diameters between 8'-300', suitable for refineries, terminals, pipeline facilities and other customers.
Tank cracks are common API Std 650 self-anchored tanks defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API Std 650 self-anchored tanks construction, which become obvious after the later use. Or in the process of using the API Std 650 self-anchored tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.
The thickness of the API Std 650 self-anchored tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.57 in. The nozzle neck is seamless steel pipe and conforms to ASTM A53, Grade A; the materials in the tank wall and reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank walls are fully radiographed, double-welded butt joints. The adequacy of the reinforcement and attachment welds shown in Figure F-7 shall be determined.To determine the length of the nozzle neck within the limits of reinforcement, the smaller of the following calculated values shall be used:(2.5)(0.625) = 1.56 in. (2.5)(0.375) + 0.75 = 1.69 in.
