API standard 650 carbon steel storage tanks toughness requirements of plates

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

The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API standard 650 carbon steel storage tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.

This standard only applies to API 650 storage tanks API standard 650 carbon steel storage tanks with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).
