Issues regarding the coloring of methane and ethylene pipelines
Thread Content
We are currently carrying out construction work on methane and ethylene pipelines. Regarding the coloring of these pipelines, I checked the document \"Basic Identification Colors, Identification Symbols, and Safety Markings for Industrial Pipelines\"; it only states that gas pipelines should be yellow. Does that mean all methane and ethylene pipelines have to be yellow as well? I was wondering if anyone has any other coloring standards? I hope to get some advice from all of you.
This isn’t very clear, but the design institute should provide coloring standards for the above two types of media
But all the colors provided by the design institute were gray. I checked the standards; we are using American technology, so it might differ from the national standards
I don’t think it’s that strict; even the natural color of stainless steel should be fine. Here, methane is represented in yellow, while ethylene uses the natural color of stainless steel
Thank you all, masters. I’ve learned a bit more: we are using imported equipment, and gray is the color used for carbon steel pipes.
