CSA G40.21 Gr 260W plates API standard 650 storage tanks

Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API standard 650 storage tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API standard 650 storage tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.

Operation points of sand blasting rust removal for metal storage tank, API standard 650 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.
