API standard 650 mixed material tanks dimensional tolerances

The heat transfer oil fin tube heating device for large API standard 650 mixed material tanks heats the circulating heat transfer oil in the shell and tube heat exchanger through high temperature and high pressure steam. The heat transfer oil exchanges heat with the medium to be heated in the storage tank through the heating coil, so as to heat the storage medium. High temperature heat transfer oil fin tube heating device has the following advantages:
1. High heat transfer efficiency
2. Reduce heating coil leakage
3. Easy to repair and maintainStamping of API 620 Storage Tank PlatesBefore plates required to be stamped by the steel mill are used, the inspector shall see that they bear the stamp. In laying out and cutting the API standard 650 mixed material tanks plates, at least one set of the original material identification markings should, if possible, be left where it will be plainly visible when the tank is completed. Should the identifying marks be obliterateSpot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.This standard establishes minimum requirements for API 650 tank material, API standard 650 mixed material tanks design, fabrication, erection, and inspection for ertical. aboveground，closed- and open-top.The company operates on the principles of fairness, objectivity, science, pragmatism and integrity.
