Abstract:
A method of manufacturing a container for holding pressurized fluids is described. Firstly, drill a first axial blind bore into a first end of a first piece of bar stock. Secondly, drill a second axial blind bore into a first end of a second piece of bar stock. Thirdly, weld the first end of the first piece of bar stock to the first end of the second piece of bar stock. This forms a container in which the first axial blind bore and the second axial blind bore cumulatively form an interior cavity. Following the teachings of the described method gas cylinders have been manufactured that can withstand pressure levels of 1800 pounds per square inch.
