Corrosion condition of the heat exchanger tube bundle
Thread Content
The media on both ends are water and water vapor; the material of the heat exchange tube bundle is 20#, the temperature is below 100 degrees, the pressure is around 0.5, and the tube bundle generally lasts for several years
How is the lifespan of such things estimated? Theoretically, it’s a few years; the information is available in the drawings. The design life of our drawings is generally 20 years. But over time, as well as the quality of the cooling water, no one knows exactly how many years it will last.:lol
The tube bundle is a vulnerable component and will not last 20 years; the shell, tube box, etc. can last 20 years. Generally, it is about 3 years; in cases of severe corrosion, the lifespan is **reduced**. Carbon steel tube bundles can be coated with non-metallic coatings for corrosion protection, and this will suffice for at least 5-6 years.
It is usually specified as 20 years; this is the period during which replacements are carried out during maintenance
Under normal circumstances, it is up to 6 years. Mainly, scaling and corrosion caused by dissolved substances in water and steam have a significant impact on lifespan.
We are not vulnerable components; I’ve checked our heat exchange tubes and tube boxes, and their lifespan is 20 years.
Generally, small leaks are sealed, while large leaks are replaced. The service life of the tube bundle is also related to the wall thickness, right?
