API standard 650 SUG III tanks design requirements

High temperature heat transfer oil fin tube heating device for large API standard 650 SUG III tanks has the advantage of high heat transfer efficiency. The high-temperature heat-conducting oil finned tube heating device adopts high-efficiency outer finned tubes. The outer finned tube coils are immersed in a water bath. Compared with ordinary light tubes, the contact area between the evaporation coils and the medium is increased. The total heat transfer coefficient of the coil is determined by the heat transfer coefficient outside the tube. This increases the heat flux per unit tube length and improves the overall heat transfer efficiency.

Facilities for API 620 storage tanks InspectorThe manufacturer shall afford the inspector all reasonable facilities for testing and inspection and shall provide mutually agreeable advance notification to permit the examiner to witness all tests of the equipment and materials during fabrication, including all laboratory tests of the material to be used and all hydrostatic and pneumatic tests at the site of erection.The API standard 650 SUG III tanks inspector shall be permitted free access to all parts of the plant concerned with the manufacture of the tank during fabrication and to all parts of the plants of material suppliers who are concerned with the manufacture of materials to be used in the tank.

API 650 sets minimum requirements for the design, material, construction, and testing for aboveground, open and closed-top, cylindrical API standard 650 SUG III tanks steel storage tanks in different capacities and sizes, roughly equating to the pressure of the atmosphere (not greater than the weight of the roof plates).
