Purchase price of second-hand inner coil tube reaction kettleThe material of the reaction kettle is mostly stainless steel, which makes it difficult for the reaction kettle to undergo chemical reactions with the medium and be corroded under normal circumstances, rather than being unable to be corroded under any conditions. Of course, in addition, everyone should also understand how to improve the surface quality of the reaction kettle and exert its corrosion resistance.

Suitable for acid pickling and passivation treatment inside second-hand reaction vessels. Under the presence of corrosive media and inducers such as scratches, splashes, and cutting slag, stainless steel can also undergo slow chemical and electrochemical reactions with corrosive media to be corroded, and under certain conditions, the corrosion rate is quite fast, resulting in corrosion phenomena, especially pitting and crevice corrosion. The corrosion mechanism of stainless steel parts is mainly electrochemical corrosion. Due to differences in production processes and operating conditions among users, stainless steel reaction vessels are divided into jacket heating types such as electric heating rod heating, steam heating, and thermal oil circulation heating. The shaft seal device is divided into packing seal and mechanical seal, and the stirring types include anchor type, slurry type, pot wheel type, push type, or frame type.

In order to save energy, reduce equipment corrosion rate, and enhance the service life of stainless steel reactors, it is necessary to regularly clean and maintain the reboiler and stainless steel reactor. Generally, we require customers to regularly clean the reboiler every year, which has achieved very good results.

These are the surface anti-corrosion treatment methods for second-hand reaction vessels. These are some issues that everyone should be aware of, and I hope you don't overlook them.
