I’m seeking help from everyone

Our facility has a storage tank used for diluting ammonia, made of carbon steel. During the process of diluting ammonia, a temperature difference of 35–50°C exists. Previously, the tank’s interior was coated with epoxy furan resin paint; however, after two years of operation, the coating has begun to peel off. I would like to ask the experts for an explanation as to why this is happening, as well as suggestions for alternative anti-corrosion solutions for the tank’s interior coating
1. At room temperature, rotational molding of PO and PE is sufficient, with a thickness of 5–8 layers. 2. If the pH value variation is not significant, 304 material can also be used, although it is more expensive.

The fundamental reason for the peeling is the coating chosen by your company, which has low adhesion strength, and the work surface was not properly prepared before construction. If it has fallen off, there is no need for repair; it is recommended to apply a new anti-corrosion coating. It is recommended to use a SEBF coating. No need to worry about it once the construction is done – it’s safe and reliable
