API standard 650 unanchored flat-bottom tank vacuum breakers

API 650 stipulates that an open tank should be provided with a wind-resistant ring to ensure that the API standard 650 unanchored flat-bottom tank tank body maintains its roundness when subjected to wind. There are no hard and fast rules for vault API 650 storage tanks. It can be determined by comparing the equivalent wall height with the maximum height of the unreinforced tank wall.

The construction period comparison of mechanical cleaning and manual cleaning for vertical storage tank, API standard 650 unanchored flat-bottom tank. The API standard 650 unanchored flat-bottom tank mechanical cleaning period is short, and the construction period is not affected by the size of the storage tank and the amount of sludge in the tank, and the cleaning equipment operates 24 hours a day. The manual cleaning of the API standard 650 unanchored flat-bottom tank has a long construction period, which is easily affected by the external environment, and the number of workers is limited by the size of the storage tank and the amount of sludge.

When roof plates, knuckle plates, compression rings, and manways and nozzles including reinforcement are primarily subjected to atmospheric temperature, the rules in API 620 oil tank standard Q.2.3 shall govern.
