Nondestructive Paint for Alloys

Nondestructive Paint for Alloys

Nondestructive Paint for Alloys

(OP)
I'm looking for a paint that is nondestructive to nonferrous alloys. I am over a site that currently has a large inventory of stainless steel pipe and different alloyed sheets of plate. The material is no longer identifiable due to the length of time it has been sitting in the elements. In order to use the correct material I am currently purchasing new material for each job. I have the ok to have all pieces PMI so the material does not go to waste.

I'm looking for a paint that can be applied the length of the pipe so I can have a color code to prevent confusion in what material is what. I'm not looking at painting the entire pipe, but rather just a simple line from end to end.

Thanks in advance!

RE: Nondestructive Paint for Alloys

If you are simply color coding material for storage in inventory to ensure traceability, all you need to use are spray paints with no halogens.

RE: Nondestructive Paint for Alloys

There are some old standards, basically this is the bottom line:

1. Contain less than 300 ppm aggregate of iron, copper, lead,
zinc, mercury, and sulfur as determined by spectrographic
methods.
2. Contain less than 200 ppm total halogens (free and chemically
combined) as determined by combustion-pyrohydrolysis treatment
of the sample, or use of an equivalent combustion technique,
and quantitative analysis of the product by titration or
specific ion electrode methods.
