A516 grade 55 plates API 650 flexible liquid storage tanks

Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API 650 flexible liquid storage tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.

The floating roof is the top cover floating on the liquid level, so the sealing performance of API 650 flexible liquid storage tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API 650 flexible liquid storage tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.

The hot weather in summer brings great security challenges to the vertical oil storage tanks, API 650 flexible liquid storage tanks standing outdoors. We must find some simple and effective methods to protect the API 650 flexible liquid storage tanks in order to make them safely spend the summer. As a API 650 flexible liquid storage tanks manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.
