Aluminum-Alloy Gas Cylinders
In this category construction, inspection and more are included for aluminum-alloy gas cylinders. These standards better balance design and efficiency with universal utility and acceptance.
ISO 7866:2012
Gas cylinders - Refillable seamless aluminium alloy gas cylinders - Design, construction and testing
ISO 7866:2012 specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes and tests at time of manufacture of refillable seamless aluminium alloy gas cylinders of water capacities up to and including 150 litres for compressed, liquefied and dissolved gases for worldwide use (normally up to +65 °C).
ISO 18119:2018
Gas cylinders - Seamless steel and seamless aluminium-alloy gas cylinders and tubes - Periodic inspection and testing
This document specifies the requirements for periodic inspection and testing to verify the integrity of cylinders and tubes to be re-introduced into service for a further period of time.
This document is applicable to seamless steel and seamless aluminium-alloy transportable gas cylinders (single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of water capacity from 0,5 l up to 150 l and to seamless steel and seamless aluminium-alloy transportable gas tubes (single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of water capacity greater than 150 l. It also applies, as far as practical, to cylinders of less than 0,5 l water capacity.
This document does not apply to the periodic inspection and maintenance of acetylene cylinders or to the periodic inspection and testing of composite cylinders.
NOTE Unless noted by exception, the use of the word "cylinder" in this document refers to both cylinders and tubes.
CGA C-6.1-2019
Standard for Visual Inspection of High Pressure Aluminum Alloy Compressed Gas Cylinders - 7th Edition
This standard has been prepared for the visual inspection of aluminum alloy compressed gas cylinders with service pressures of 1800 psi (12 410 kPa) or greater.
CGA C-6.3-2019
Visual Inspection of Low Pressure Aluminum Alloy Compressed Gas Cylinders - Fourth Edition
This publication covers the periodic inspection of aluminum alloy compressed gas cylinders with service pressures of 500 psi (35 bar) or less. This publication may not cover all circumstances for each individual cylinder type or lading. Inspection agencies may find it necessary to amplify these requirements to fit their condition of service if the service is more severe than encountered in transportation
