Gas cylinders of composite construction - Specification and test methods - Part 2: Fully wrapped fibre reinforced composite gas cylinders with load-sharing metal liners
|Publication Date:||1 June 2002|
|ICS Code (Gas cylinders):||23.020.35|
This part of ISO 11119 specifies requirements for composite gas cylinders up to and including 450 litres water capacity, for the storage and conveyance of compressed or liquefied gases with test pressures up to and including 650 bar. The cylinders are constructed in the form of a seamless metallic liner over-wrapped with carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a resin matrix, to provide circumferential reinforcement. This part of ISO 11119 addresses fully wrapped composite cylinders with a load-sharing liner (i.e. a liner that shares the load of the overall cylinder design) and a design life from 10 a to non-limited life. For cylinders with design life in excess of 15 a, and in order for these cylinders to remain in service beyond 15 a, requalification of these cylinders is recommended.
