Alclad 3003 aluminum plate API 650 stainless steel storage tanks

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.

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API 650 stainless steel storage tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.

We exported 352 tons SA387GR12CL2 steel plates to Vietnam. The Vietnam customer needed the SA387GR12CL2 steel plates for their tank fabrication project urgently. We are world class steel materials supplier and exporter. Other than regular fresh production, we also keep huge stocks, so as to meet urgent demands of our customers. For the 352 tons SA387GR12CL2 steel API 650 stainless steel storage tanks plates, we collected from our warehouse and it only took us 3 days to arrange delivery. The customer was really impressed by our rapid shipping and spoke highly of our SA387GR12CL2 steel plates quality after use.

Usually, the soil resistance of the foundation should be considered before the design and construction of API 650 stainless steel storage tanks. The soil endurance in the API 650 stainless steel storage tanks construction area plays a decisive role in the basic cost of the tank. In areas with high soil resistance, not only the cost of foundation treatment can be greatly reduced, but also the ratio of height to diameter of storage tank can be obtained. Therefore, the investment cost of the API 650 stainless steel storage tanks can be greatly saved in the area with large soil resistance.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel API 650 stainless steel storage tanks plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
