API Std 650 mechanically-anchored steel tanks with a mat foundation

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.

API 650 is the standard for welded tanks for oil storage. It specifies the API Std 650 mechanically-anchored steel tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.

We have lots of successful cases, for example in July 2015, we exported 5714 tons ASTM A36 mild steel plate to Peru. After receiving the plates and putting then into use, our customer spoke highly of the ASTM A36 mild steel plate quality. In addition, the customer also introduced us an Venezuela customer, who bought 933 tons A36 steel API Std 650 mechanically-anchored steel tanks plate from us. And then in Mar. 2016, due to the first cooperation in July 2015 is very successful. The customer is very satisfied with our product quality and comprehensive service. This time, the customer place an 3989 tons order directly.

The main content of the inspection of the safety management of metal atmospheric API Std 650 mechanically-anchored steel tanks is whether the filed data of the storage tanks are complete; whether the operators have received safety management training; whether the problems detected in the past have been resolved. The main inspection content of the tank body of the metal atmospheric pressure storage tank is whether the tank top, tank wall, and bottom plate of the storage tank are deformed, dented, seepage and perforation, etc.; whether the API Std 650 mechanically-anchored steel tanks accessories are complete and whether there are any abnormalities; No sinking, tilting, etc.

The results of adopting two-level API Std 650 mechanically-anchored steel tanks service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and API Std 650 mechanically-anchored steel tanks after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
