ｂよりポンプｃにより払出し得るようになつてい
る。 A conventional storage tank will be explained with reference to Figs. 1 and 2. The one shown in Fig. 1 is a storage tank for oil, etc., and the oil can be discharged by a pump c from a pipe b fixed to a side plate a of the tank. The second
The one shown in the figure is a storage tank for low-pitched liquefied gas.The low-pitched liquefied gas can be discharged by a pump c from a pipe b fixed to the tank side plate a, passing through a heat insulating material d wrapped around the outer circumference of the tank side plate a. It's getting old.
しかしながら、前述の貯蔵タンクにあつては、
何れも、配管ｂをタンク側板ａに固着しているた
め、地震時に、配管ｂとタンク側板ａとの接続部
にひび割れが生じ、そこから液体が流出して大き
な事故が生じるおそれがある。 However, in the case of the storage tank mentioned above,
In either case, since the pipe b is fixed to the tank side plate a, there is a risk that cracks will occur at the connection between the pipe b and the tank side plate a during an earthquake, and liquid will flow out from there, causing a major accident.

雑さは一層増し、且つN2ガスパージのための設
備が必要となるから維持費が高価となる。 Therefore, in order to solve the above-mentioned drawback, as shown in Fig. 3, there is a system in which a pipe f having an inner diameter slightly larger than that of the submerged pump e is inserted into the tank from above, and the pipe is discharged by the submerged pump e. However, since this tank does not have a through hole in the tank side plate a, the safety in the event of an earthquake is improved compared to the storage tank shown in FIGS. 1 and 2. However, during maintenance, the submersible pump e must be lifted upward through the pipe f, making the work complicated and requiring a long time for maintenance. In order to prevent vaporization, the work must be carried out while purging N2 gas from above the pipe f, which further increases the complexity of the work, and requires equipment for purging N2 gas, resulting in high maintenance costs. Become.
