Fabricated to API Standard 650 Welded Tanks for Oil Storage Shop Assembled API standard 650 aluminum tanks Storage Tanks, these tanks are commonly used at oil and natural gas terminals, API standard 650 aluminum 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.

Inspection of weld and micro crack of API standard 650 aluminum tanks: the inner and outer surface of API standard 650 aluminum tanks, weld and heat affected zone shall be observed by naked eyes first. 100% ultrasonic testing or 100% penetrant testing are carried out for butt welds of API standard 650 aluminum tanks. For the defects found by 100% magnetic particle inspection, dye detection, 100% ultrasonic inspection or 100% penetrant inspection, the radiographic inspection shall be used again to ensure the accuracy of the test results.
