Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API Std 650 self-anchored tank floating roof. 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.
When the day light gradually decreases, the temperature of oil in the API Std 650 self-anchored tank will also decrease, the evaporation speed will gradually slow down, and the pressure in the API Std 650 self-anchored tank will also decrease. When the pressure in the API Std 650 self-anchored tank is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API Std 650 self-anchored tank through the open vacuum valve, which is the "suction" process of the oil tank.
The hardness of the welds contacting these environments, including the heat-affected zones, shall be considered. The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API Std 650 self-anchored tank manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.
