above ground painting systems for pipelines (Natural Gas)
(OP)
Hello guys, good morning
I hope you are well and had a great thanksgiving if you celebrated.
I have a question about if you have seen a table where you could check the different types of environmental and you could check what is the best system of painting for above ground painting? I remember that I saw something like this in API or ASME but I hope you could help me please with this.
Thank you so much, have a great day

What do you mean by "different types of environmental"?
Define "best" - cheapest?, longest lasting? easiest to apply? nicest colour?
Factory applied or site applied? surface preparation makes a big difference.
As does temperature of the pipe or the location.
Basically too many variables to have a simple chart.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

System Number: 1 / Application: If the environmental is salty and humidity with temperatures of 80 Celsius / Surface preparation: Near white blast cleaning / Primer coat: Polyamine/ Intermediate coat: None / Finish coat: Polyamine epoxy 4 mils.
But I thought that was from ASME or API, maybe is from each painting company or maybe as you said company standards.
Thanks

The charts that I have seen were end user specific.
They usually had three classes of service (arid with high UV, marine/coastal, all else).
They were all three layer systems with IOZ base.
The coating thickness, main coat, and top coat were slightly different based on service.
They tried to offer two options for each coating.
Sometimes there were special notes about 'extended sub-freezing service'.
I have seen technical papers where people compare different coating systems.
The problem is that often in one region you can't buy the same materials as in another.

You may need other systems for repair or marginally prepared surfaces but this is for new construction, right?
As Ed alluded to, regional available is going to dictate the exact products used.

Thanks to everyone, I found an image in Spanish that I used to use in Mexico in my old work, but I would like to found something in English.
I think that everything comes from ISO as BCD said.
Thanks
