The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage 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 650 floating-roof tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API 650 floating-roof tanks, static storage loss and dynamic liquid level loss are common losses.

In addition to the requirements of API Standard 620 tank Appendix Q.8.1, the nameplate shall be attached to the tank at an accessible location if it is outside of any insulation or protective covering of the tank.
