Abstract
A corrugated constant pressure cylinder apparatus having no micro leaks and its method of use. The internal pressure of the corrugated cylinder (b10) is maintained at a constant pressure so as to allow for transport or storage in a state without micro leaks. The corrugated constant pressure cylinder apparatus is able to keep substances that exist in gaseous or liquid form at room temperature such as mixed refrigerant gases, volatile organic compounds (VOC), hydrocarbon mixtures-in liquid form, or is able to keep the pressure constant even if the internal volume changes due to the contents inside the cylinder.
