Corrosion Inhibitor
Corrosion Inhibitor
(OP)
Not sure if this is the place to ask but thought as good as any.
We have a project coming up that will cause some ASME carbon steel boiler equipment to be stored outside for expectedly 6 months and perhaps longer in full blown, cold (think snow) winter environment. All equipment to have all openings capped but I think we need some type of corrosion inhibitor. My ultimate goal is to avoid pitting.
Lots of different stuff out there to choose from. The supplier/fabricator) has reccomended the use of Cortec vpCI 649 mixed in with the hydro water. Reading brochures I am not convinced this is the best choice. A nitrogen purge adds a significant cost to this as does dry storage.
Do any of you have any success stories using other medium?

I would hazzrad a guess that paying for storage (which may not even be requried) would be cheaper than paying for any corrossion inhibitators, or any remedial work requried later.
Just my thoughts.

We used VPI, vapor Phase Inhibitor, along with bagging and boxing. If you decide to go in house here is some products from Cortec that will do the job.

better than hydro liquid.
