API Std 650 aboveground petroleum storage tanks hydrostatic testing requirements
The thickness of the overburden on the top of the API 650 oil tank should not be less than 0.5m. The surrounding backfill with clean sand or fine soil should be no less than 0.3m thick; the API 650 oil tank API Std 650 aboveground petroleum storage tanks operation platform ladder selection unit is considered in a unified manner. The buried operation well is designed for buried horizontal oil tanks, and the two are compatible.
The tank shall be filled with water to the design liquid level unless height is limited as noted in API 620 standard Q.8.1.
