COMPLEX GAS BOTTLE, WHERE PARTIALLY OR COMPLETELY IS USED ALREADY KNOWN BOTTLE UNDER PRESSURE FOR COMPRESSED, LIQUID OR DISSOLVED GASSES AND THE PRODUCTION PROCEDURE THEREOF

摘要

The present invention relates to a composite cylinder, comprising a liner, which is wrapped over a substantial part of its length with composite fibers, characterized in that the liner is a pre-existing preformed second hand pressurized-gas cylinder for compressed, liquefied or dissolved gases. There is also disclosed a process for producing a composite cylinder for a higher filling pressure, comprising providing a liner and wrapping the liner over a substantial part of its length with composite fibers, characterized in that the liner is provided in form of a pre-existing preformed second hand pressurized-gas cylinder for compressed, liquefied or dissolved gases, with a lower filling pressure.
