How to solve the oxygen corrosion of fin tube by fin tube manufacturer
- Jan 24, 2018 -

At present, the management level, the technical level and the capital ability of our country are unable to meet and adapt to the advanced deaeration and softening technical requirements. Therefore, the oxygen content in the heating water is much more than the standard, which leads to the corrosion of the fin tube directly. Therefore, how to solve the problem of the corrosion of the finned tube under the condition of oxygen containing medium is of great significance in our country. According to the current situation, experts said: Tonghao solution oxygen corrosion of tube fin can be considered from the following aspects:


(1) the design of heating system should avoid the connection of the system with the large oxygen as far as possible. That is to say, as close as possible, such as the location of the exhaust cock, the closure of the circulating pump, etc., and at the same time, the low pressure should be avoided during the operation of the equipment, which avoids unnecessary water loss.


(2) the addition of water must be deoxidized.


(3) heating water and corrosion inhibitor.


(4) when the heat is stopped, the fin tube is filled with dry or deoxygenated water.


(5) when the newly installed finned tube is pressed, the water pressure experimental medium should be added to the water solvent and the non toxic antirust agent.
