6061 aluminum shapes API standard 650 self-anchored flat-bottom steel tanks

The interior of API 650 storage tanks to be internally lined or coated must have all edges rounded to a minimum of 3 mm radius. Internal welds must be completely seal welded, ground smooth, and free from API standard 650 self-anchored flat-bottom steel tanks surface porosity, pockets, and high spots. Remove weld spatter. Vendor as specified on API 650 storage tanks drawing must perform additional surface preparation.

API standard 650 self-anchored flat-bottom steel tanks construction must adhere to the design drawings, acceptance specifications and construction plans. If the design needs to be modified during API standard 650 self-anchored flat-bottom steel tanks construction, it must be approved by the original design unit or Party A’s representative and relevant personnel of the supervision unit, and written visa procedures must be completed in advance. The equipment and main materials used in the oil tank construction project must have certificates of conformity and quality assurance.

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.

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API standard 650 self-anchored flat-bottom steel tanks steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
