The construction of foundations for API Std 650 stainless and carbon steel tank

Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API Std 650 stainless and carbon steel tank are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API Std 650 stainless and carbon steel tank, static storage loss and dynamic liquid level loss are common losses.

Responsibility of API 620 storage tanks ExaminerThe inspector shall ensure that all materials used in tanks constructed according to the rules in this standard comply in all respects with the requirements of these rules. This shall be done either by witnessing mill tests or examining certified mill test reports supplied by the Manufacturer. Storage tanks API Std 650 stainless and carbon steel tank constructed according to the rules in this standard shall be inspected and tested in accordance with the sections that follow. The inspector shall carefully follow the fabrication and testing of each tank and shall make sure that they comply in all details with the design, fabrication, and tests specified in these rules.

Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API Std 650 stainless and carbon steel tank wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.
