Oxygen color issue

2016-08-15View Original

Thread Content

Recently, something has confused me: oxygen cylinders on the market are red, while acetylene cylinders are green. Why isn’t it the same according to standard GB2550-2007? Could it be that there have been changes required by GB2550-2016? Does anyone have the new standard (GB/T2550-2016)? It’s not available for download yet; I’m seeking help from experts.

I don’t understand; is it the color of the gas itself?

That is non-compliant; it’s likely counterfeit and of poor quality. Oxygen is blue, acetylene is red
