Transportable gas cylinders — Compatibility of cylinder and valve materials with gas contents — Part 4: Test methods for selecting steels resistant to hydrogen embrittlement
| 분야 | ISO/TC 58 : Gas cylinders |
|---|---|
| 적용범위 | ISO 11114-4: 2017 specifies test methods and the evaluation of results from these tests in order to qualify steels suitable for use in the manufacture of gas cylinders (up to 3 000 l) for hydrogen and hydrogen bearing embrittling gases. This document only applies to seamless steel gas cylinders. The requirements of this document are not applicable if at least one of the following conditions for the intended gas service is fulfilled: - the working pressure of the filled embrittling gas is less than 20 % of the test pressure of the cylinder; - the partial pressure of the filled embrittling gas of a gas mixture is less than 5 MPa (50 bar) in the case of hydrogen and other embrittling gases, with the exception of hydrogen sulphide and methyl mercaptan; in such cases, the partial pressure shall not exceed 0,25 MPa (2,5 bar). NOTE In such cases, it is possible to design the cylinder as for ordinary (non-embrittling) gases. |
