Abstract
Composite cylinder assembly includes a removable liner assembly consisting of a liner member having circumferential hoop stress windings wrapped thereabout. The ends of the liner assembly freely float on cylindrical end portions on the inner ends of end glands at opposite ends of the cylinder for sliding sealed engagement with ring seals contained in external grooves in such cylindrical end portions. Surrounding the removable liner assembly in radially spaced relation therefrom is a composite outer wall portion having opposite ends threadedly connected to the end glands radially outwardly of the removable liner assembly, whereby disconnecting the ends of the outer wall portion from the end glands will permit removal of the liner assembly as well as the liner seals and outer wall portion for refurbishment and/or replacement as desired.
