Problems with the material of oil cooling pipes in refrigeration units
Thread Content
The oil-cooled heat exchanger pipes of Freon refrigeration units mostly use copper pipes and stainless steel. However, it is said that chlorine corrodes stainless steel, so it is better to use carbon steel for oil cooling. The circulating water generally contains chlorine. I don’t know if this statement is correct?
In fact, just use ordinary carbon steel heat exchange tubes. If the chloride ion content in the cooling water is too high, you can use nickel-nickel copper.； This post was last edited by jia717 on 2009-4-15 17:49 ]
Corrosion is relative. The flow rate of fluid directly affects the corrosion of equipment. Even the best materials will corrode if the fluid does not circulate for a long time. Management must be strengthened on this point.
