Painting pipe to reduce corrosion
Painting pipe to reduce corrosion
(OP)
Has anyone else faced the challenge of getting pipe painted when noone wants to put $ in the budget?
First of all - does paint really matter on process piping?
Have there ever been any catastrophic incidents caused by corrosion due to a lack of painting/surface protection of the pipe? I have not come across any nor heard of any through the Chemical Safety Board.

Is it in a corrosive atmosphere?
If so, What is that corrosive atmosphere?

Another facility I was at had about 50' of benzene piping fall out of an elevated rack.

Consider the cost of stainless steel piping, if the owner does not want to paint the pipe. He may then include some budget for coating /maintaining the paint on the pipe and the structure.
Some steel vent stacks have been justified to be installed in stainless steel instead of carbon steel. The cost of painting work at elevated heights resulted in a definite payback of the added cost for stainless steel.

1. Mechanical integrity risk
2. Aesthetics
With 1, try finding some atmospheric corrosion rates for the location and then bring in some pollutant, time of wetness and temperature factors and see what the implications are for metal loss over the design life. Analysis of inspection data will also help you build a picture.
2 is probably the most important. Who wants to take pride and put a good day's work in at a plant that looks a total rust bucket?

What is CUI?
Pennpiper: The atmosphere is generally non-corrosive - it's just outside.
Ash9144 : Was the pipe being used when the 50' fell out of the rack?
RE: Painting pipe to reduce corrosion
The benzene line had started leaking. We had just shut down the transfer to check it. When first piece of insulation was removed, it brought the 50' of pipe with it.
