API standard 650 SUG I tanks subject to a small internal pressure

API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API standard 650 SUG I tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.

The cleanliness of the API standard 650 SUG I tanks has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API standard 650 SUG I tanks clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API standard 650 SUG I tanks is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.

Design of Reinforcement for Single Openings in Tank Walls
The 20 in. x 29 in. obround manhole shown in Figure F-5 is located in solid plate in the sidewall of a cylindrical storage tank 45 ft in diameter in an area where the thickness of the wall plate, tw, is 1/2 in. No corrosion allowance is required. The total internal pressure, Pl + Pg, at the horizontal centerline of the opening is 27.5 lbf/in.2 gauge. The thickness of the wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.485 in. The manhole neck is fabricated by welding from 3/8 in. plate. The materials in the API 620 tank wall, the manhole neck, and the reinforcing pad conform to ASTM A516 Grade 60. The joints in the welded steel storage oil tank wall and the longitudinal joint or joints in the manhole neck are double-welded butt joints, spot radiographed in accordance with 7.16 and 7.17.

We can process the steel materials according to your drawing. Or if you can not make drawing, please send us API standard 650 SUG I tanks specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.

In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver API standard 650 SUG I tanks goods in time and smoothly.
