May I use galvanized steel pipes for cooling circulating water and chilled water? Is it useful? What material are you using?
…………For cooling, carbon steel welded pipes should work fine for the circulating water; for chilled water, we use grade 20 seamless pipes…………:)
What problems might arise with galvanized ones? ?
Cooling water usually uses carbon steel, while cooling water systems can generally use stainless steel.
It depends on whether you have any requirements regarding water quality; if so, 304 material can be used, while carbon steel is sufficient if no such requirements exist. Galvanizing is generally used for tap water pipes
Use seamless carbon steel pipes, as the addition of chemicals and similar substances can cause scaling on the inner walls of the pipes
Now, **it is required that galvanized pipes not be used, mainly due to corrosion and the resulting blockages**
For circulating cooling water, seamless carbon steel pipes are generally used. As for chilled water, I’m not sure whether it refers to ordinary low-temperature water (above the freezing point); if it is brine-based chilled water, carbon steel is prone to corrosion. For low-temperature chilled water, I recommend using an ethylene glycol aqueous solution as the cooling medium; in that case, using carbon steel seamless pipes will be no problem.
Hello! Which document specifies that galvanized pipes cannot be used? I had seen many people say that before, but I couldn’t find the source. Thank you!
There are usually no problems; ordinary seamless pipes will work just fine. I would like to ask you, what medium do you use for chilled water? If it’s saltwater, its corrosiveness is relatively high; I use an ethylene glycol aqueous solution here. I hope this can help you.
