I’d like to ask about the standard number for American standard oxygen valves
Thread Content
The standard for oxygen valves specified by the Ministry of Machinery is JB/T 12955. I would like to know what is the standard number for oxygen valves according to American standards?
The U.S. standard for oxygen valves is CGA G-4.1 (Compressed Gas Association Standard for Cleaning Equipment for Oxygen Service); you can refer to this standard. .
I took a look at the CGA G-4.1 standard; this standard refers to the cleaning standards for oxygen-using equipment. The scope of exemptions for valve materials used for oxygen is not mentioned.
I have come across steels used for high-temperature, high-pressure hydrogen-related operations in API 941 oil refineries and petrochemical plants
Is this the ASTM G94 standard for evaluating metals used in oxygen supply equipment?
The standard number for American standard oxygen valves is: CGA V-9:2017 – Oxygen Systems. ISO 7291:1999 – Safety requirements for oxygen valves. EN ISO 10297:2014 – Standard for oxygen valves.
