API standard API Std 650 special tank

There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API Std 650 special tank tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API Std 650 special tank edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.

The engineering quality of API Std 650 special tank not only affects production and operation, but also affects the life safety of the staff. The factors affecting the API Std 650 special tank construction quality are all aspects, any link, any part of the problem will affect the whole project, so the quality management is paid more and more attention. How to ensure the engineering construction quality of oil tank? First, make API Std 650 special tank construction technical preparation carefully, understand the design intent, master the construction acceptance specification, and make detailed construction technical disclosure to the construction team.

The thickness of the API Std 650 special tank 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.
