A573 Gr 450 plates API standard 650 welded steel oil storage tanks

Operation points of sand blasting rust removal for metal storage tank, API standard 650 welded steel oil storage tanks:
1. The equipment should be as close as possible to the workpiece to be processed, so as to reduce the pipeline length and pressure loss, avoid excessive pipeline wear, and facilitate the construction personnel to contact each other.
2. The jet pipe should be straight as much as possible to reduce the concentrated wear at the bend. The wear direction of the bend should be changed frequently to prolong the service life of the pipe.
3. Strictly control the process parameters.

Stamping 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 welded steel oil storage 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.

Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API standard 650 welded steel oil storage tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.
