API Std 650 ambient temperature tanks roof ladder

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 ambient temperature 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.

All oil tanks have service life. Due to the pressure of the oil stored on the tank and the corrosion of the oil and external environment on the tank, the oil storage tank will gradually become thin or crack after a long time. Due to the different materials and environment of API Std 650 ambient temperature tanks, the consumption of API Std 650 ambient temperature tanks is different, so it should be taken into account when evaluating the remaining service life of API Std 650 ambient temperature tanks.

The thickness of the API Std 650 ambient temperature 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.
