Treatment of heat exchange tubes in ammonia condensers

I’ve encountered a problem recently: there are 2 ammonia condensers, with dimensions of Φ57×35 and a length of 5175. The tubes need to be sandblasted for rust removal, followed by four coats of phenolic varnish. What is the cost associated with such treatment?

The heat exchange tubes of ammonia condensers are generally made of stainless steel, right? If it is carbon steel, we usually ask the supplier to do it during procurement, and then have it packaged cleanly before shipping. As for how much the price differs from the regular one, it’s not entirely clear.

Is tubular still used for ammonia refrigeration? Why not use a plate type? There are no such problems
