What material should be used for the topcoat of this cold flare tank?
Thread Content
For cold flare separation tanks, the operating pressure is less than 1 kilogram, and the operating temperature ranges from room temperature to -110 degrees Celsius. The paint to be applied should be silver-gray, and the material of the tank is 0Cr18Ni9. I have the following questions: 1. What kind of paint should be used? 2. Does stainless steel not require an undercoat? 3. What technical requirements should be met regarding the topcoat? 4. Most importantly, the previous coat peeled off in large parts when the temperature of the tank dropped; was this due to an incorrect painting process or a problem with the quality of the topcoat? How can this be avoided?
Stainless steel storage tanks do not require painting
Reply to 1# zxl198217: Generally, stainless steel does not require painting, and paint applied to its unprocessed surface has poor adhesion. Regarding the issue of your paint peeling off, how long has it been since it started to peel? Is the temperature changing frequently? Was the surface treated before painting?
