200ft diameter API Std 650 flat-bottom steel tanks

The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API Std 650 flat-bottom steel tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API Std 650 flat-bottom steel tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.

Crack treatment of API Std 650 flat-bottom steel tanks weld area: find out the crack tip with ray or ultrasonic flaw detection, drill cut-off holes at both ends of the crack with the cut-off method, the hole depth is slightly greater than the crack depth, or groove (crack stop groove) is made by angle grinder at both ends of the crack, shovel and grind the whole crack, and grind it into a suitable groove; use radiographic inspection and dye detection to verify that the crack has been completely excavated, and finally repair welding.

Structural shapes of 9% and 5% nickel steel may be furnished to the chemical and physical requirements of ASTM A353, A553, or A645. Physical tests shall be in accordance with the requirements of ASTM A6.
API Std 650 flat-bottom steel tanks used Piping, Tubing, and Forgings
Material used for piping, tubing, and forgings shall be compatible in welding strength, and thermal expansion coefficient with the tank shell material. In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.
