Question: Does an arch-shaped tank used for storing hot water require anti-corrosion treatment?
Thread Content
This tank is a dome-shaped tank, and the temperature of the hot water is 90. Can Q235B be used? Is corrosion protection needed? If I use it, what would be good? I see that many hot water tanks use 304 material; is it really necessary?
Using carbon steel will cause severe corrosion and has a certain impact on water quality. The inner wall can be coated with polymer materials for corrosion protection, which is convenient and practical, offering excellent cost-performance. Low cost. Contact is needed.
Recommended solution: Remove rust, then apply food-grade anti-corrosion paint 4 times!
The key is the requirements for water quality in the subsequent processing steps; for example, in titanium dioxide production, carbon steel cannot be used for the water preheating tanks, as later processes require certain specifications regarding the iron ion content in the water.
There are no special requirements regarding water quality. What kind of anti-corrosion material is needed for Q235B?
A polymer material can be used as a coating to prevent direct corrosion of the core material. The construction process is simple: after rust removal from the surface, it can be painted directly, and the company can carry out the work on its own. Contact is needed.
