Is anti-corrosion treatment required for the inner wall of carbon steel water storage tanks? a
Thread Content
One of our company’s 100m³ hot water storage tanks is made of Q235 material; is it necessary to apply anti-corrosion treatment to its inner wall? There is no design for it; if it is to be created, it would be better to use a corrosion-resistant version ；
Depending on the operating conditions, if the process has no special requirements regarding the water source, such as in titanium dioxide production where strict limits are imposed on iron ions, anti-corrosion measures are necessary; coatings or other non-metallic anti-corrosion materials can be used for this purpose.
For materials of ordinary quality, the inner surface should be treated for corrosion resistance; after sandblasting to remove rust, anti-rust paint should be applied
Thank you all. I was wondering if there are any equipment design specifications regarding which types of equipment are used to hold which types of media, and whether there are requirements for anti-corrosion treatment on the inner walls；
An important step in equipment management is to minimize potential hazards. Water has low corrosivity, but over time corrosion can become significant. If very high-quality materials are used, the cost will inevitably be high; therefore, I recommend using ordinary materials and applying anti-corrosion treatments to the inner walls. Overall, this offers a good cost-performance ratio. Our company has very practical technologies; for more details, please contact 13782829353
First, it is necessary to consider whether there will be an impact on the manufacturing process； Second, it is necessary to consider whether the presence of corrosive substances in the water affects the service life of the equipment.
