API standard 650 SUG II tanks tank joints

After using for a certain period of time, it is necessary to check the corrosion protection of the metal oil tank and paint the outer wall of the API standard 650 SUG II tanks with anti-corrosion paint. The inlet and outlet valves of API standard 650 SUG II tanks shall be inspected and maintained regularly to ensure they are in good condition. Oil tank will produce a lot of dirt when it is stored for a long time. Usually, the cleaning cycle of metal oil tank is about three to five years.

Temperature Range: The provisions in this appendix are considered suitable for API standard 650 SUG II tanks design metal temperatures from + 40°F to –60°F, inclusive. In general, refrigerated tank primary components include those components whose failure would result in leakage of the liquid being stored, those exposed to the refrigerated temperature, and those subject to thermal shock. Further definitions of such components are provided in API Standard 620 tank R.1.4.2 and R.1.4.3.

Fabricated to API Standard 650 Welded Tanks for Oil Storage Shop Assembled API standard 650 SUG II tanks storage tanks, these tanks are commonly used at oil and natural gas terminals, API standard 650 SUG II tanks processing plants, and midstream facilities located along pipelines at the pumping, compression, or metering stations. API 650 storage tanks are designed and fabricated considering operating pressures up to 2.5 PSIG, corrosion allowance, wind loading, and seismicity.
