How many years is the typical service life of an external heat exchanger tube bundle? Does it need to be taken out for inspection every time it undergoes major maintenance?

A question from a fellow enthusiast: I would like to ask the experts, how many years is the typical service life of external heat exchanger tubes? We’ve had it for 11 years; we want to replace it, but are worried about wasting it, so we’re hesitating……

By looking at the design drawings, the service life of the tube bundles should be indicated there; it also depends on the material of the tube bundles. For example, the drawing specifies that the service life of carbon steel tube bundles in floating-head heat exchangers is 3 years.
The tube bundle pays for itself after about 3 years of use. To ensure stable and optimal growth, replacement is recommended. :lol
No maintenance for three years, and then replace it when it’s maintained? ? ? ?
The external heat exchanger tube bundles of our catalytic cracking unit were replaced once each in 2014 and 2020. It wasn’t replaced because of a problem; it was replaced to ensure no problems would occur.
