caption_attribution_description: English: Oxygen and MAPP gas compresed gas cylinders with regulators. The high pressure side of the oxygen regulator reads 1,000 PSI (69 bar). The tremendous pressure inside the oxygen cylinder (over 2,200 PSI (152 bar) in a full tank) requires extrusion as a manufacturing process and these tanks may never be welded. The lower pressure MAPP cylinder was welded together and the seam is visible where the yellow and white paint meet.
context_page_description: A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.
  The term cylinder in this context is not to be confused with tank, the latter being an open-top or vented container that stores liquids under gravity.
