An overview
From its inception in 1852, the ‘envelope’ that
contains gas under pressure, a gas cylinder as we know it today has evolved from a brazed copper sphere, to a complex shaped composite vessel. In the past 150 years, gas cylinders have populated our planet, from applications deep on the ocean beds to those in space, such that there are well over 200 million high pressure gas cylinders in use today.
This is the first in a series of articles which will demonstrate how gas cylinders have dominated our lives and will continue to play an ever increasing role. Future articles will develop on the following themes:
•Cylinder manufacturing
•Re-testing
•Regulatory/standards and use
•Aspects of gas cylinders
•Globalisation.
In particular, the globalisation of the gas cylinder market will be covered by demonstrating the powerful impact of regulations supported by relevant ISO (International Standards Organisation) standards for both their construction and subsequent use across international boundaries.
