The foundation, venting equipment, or other conditions may limit the water filling to a lower rate. Pressure shall not be applied above the surface of the water before the tank and its contents are at about the same temperature.There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API Std 650 aluminum tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation.
