Insulation exposed to rain water
Insulation exposed to rain water
(OP)
Dear all,
Our plant using a ceramic fiber blanket used to insulated steam line. During instalation the insulation was exposed to heavy rain water. The fiber insulation is severely wet because of that.
My question:
-should we replaced the insulation? what is the cause? Can we just put it in dryer to remove the water?
- some people say the insulation contain chloride that can enhance corrosion in piping system. It is true?
- could someone give me any insulation practice literatur?
Thanks for all of your help

RE: Insulation exposed to rain water
The data sheet of insulation material should indicate the leachable chloride.
RE: Insulation exposed to rain water
The insulation probably has no chlorides.
Recommend that you contact the supplier for installation instructions.
You can probably just let it dry out in-place and then put the covers over it.
