Is it because the medium at that time is different?

Different media have varying levels of corrosivity, which determines the materials that should be used. Furthermore, for the same medium, different manufacturers may use different materials, as long as they do not corrode rapidly.

Is the alkali also in the scrubber tower? The design team did not standardize the materials used; in fact, stainless steel would work fine in all cases!

It’s not supplied by one company, right? Stainless steel is a bit more expensive, but in most cases, carbon steel is used if it’s available
