Manufacturing method for membrane pressure vessel |
| abstract |
A method of making a membrane pressure vessel is disclosed. A method of manufacturing a membrane pressure vessel includes the steps of: (a) connecting an upper nozzle and a lower nozzle in a state where an upper nozzle and a lower nozzle constituting a membrane pressure vessel are fixed with a jig being spaced apart, (B) placing and fixing the inner tank of the step (a) in an outer tank installed in a work space, and (c) installing a spray pipe inside the inner tank And injecting liquid nitrogen into the inner tank through a spray pipe to heat-shrink the inner tank; and (d) injecting powder insulator into the heat insulating space formed between the inner tank and the outer tank of the step (c) (E) after the step (d), using a spray pipe in a state in which the upper nozzle and the lower nozzle are closed, a step of holding the heat insulating space in a vacuum state by using a vacuum pump Injecting the nitrogen gas at a high temperature over the inner tank and a step of expanding the inner tank. |
