Material selection for steel chimneys
Thread Content
The flue gas contains 10% water, with a sulfur dioxide content of 100 mg/NM3; it is at atmospheric pressure and the maximum temperature is 80°C. Can 316L or 2205 be used?
Look, what about adding a cooling mechanism and using PP material?
How expensive is 316l? Applying an anti-corrosion coating to the inner surface should be a good option.
Q235B+glass flake anti-corrosion
Now, titanium-steel composite panels are used in the chimneys of thermal power plants.
It is best to use non-metallic materials such as fiberglass
Carbon steel will suffice; use the photocurable nanosheet solution for corrosion protection. Contact 13110980857 for details
Carbon steel or concrete chimney, with an anti-corrosion coating on the inner surface; requires no maintenance for over 10 years.
Fiberglass or other non-metallic materials can be considered; currently, fiberglass is quite common and its price is lower than that of metallic materials
A carbon steel lining with fiberglass reinforced plastic is more suitable.
