The present invention relates to a corrugated constant pressure cylinder apparatus having no micro leaks and its method of use, and more specifically, a corrugated constant pressure cylinder apparatus having no micro leaks and its method of use where the internal pressure of the cylinder is maintained at a constant pressure so as to allow for transport or storage in a state without micro leaks. Therefore, this invention relates to a corrugated constant pressure cylinder apparatus having no micro leaks and its method of use where mixed refrigerant gases, volatile organic compounds (VOC), hydrocarbon mixtures, and other such substances that exist in gaseous or liquid form at room temperature are kept in a cylinder that maintains a constant internal pressure to keep the contents in liquid form, or is able to keep the pressure constant even if the internal volume changes due to the contents inside the cylinder.

In order to fulfill the aforementioned purpose, the corrugated constant pressure cylinder apparatus having no micro leaks of the present invention is characterized by being comprised of a fixed plate (100) comprised of a circular steel plate with a fixed thickness that has a sample inlet (101) in the middle that goes through the plate, and is coupled with the bottom portion of a cylinder (200) to form chamber (a) and; a cylinder (200) comprised of a steel tube open at the bottom section and closed at the upper section with the flared bottom section comprised of a flange (210) that has a plurality of fastening holes (211) going through it and is coupled with the aforementioned fixed plate (100) to form chamber (a) and; fastening bolts (300) and fastening nuts (300) that fasten together with bolts the aforementioned fixed plate's (100) inner side with the outer side of the flange (210) on the bottom section of the aforementioned cylinder (200) to form chamber (a) and; a pressure gauge (400) coupled to the coupling pipe (226) of the pressure gauge coupling hole (224) that checks the pressure within chamber (a) in order to control the amount of inert gas that is injected and; opening/closing valves (500) connected to the sample inlet (101) and the inert gas inlet (223) and; a sample chamber (b) inside the aforementioned chamber (a) that stores the collected sample and creates and maintains constant pressure.

In addition, the method of use for the corrugated constant pressure cylinder having no micro leaks of the present invention is characterized by collecting a fixed amount of the sample in sample chamber (b) then closing
