Minimum operating temperature for galvanized steel pipes
Thread Content
The compressed air pipelines are supposed to be made of galvanized steel pipes, but during the review it was mentioned that winters in Shandong are quite cold, so such pipes won’t work; I couldn’t find any information on this online either

I’m not sure what standard and what material the galvanized pipe you’re referring to is made of; the specifications for the design of compressed air pipelines should indicate the temperature range suitable for such materials.
For example, Q235B, Q235C\ D\ E at minus 10 degrees, minus 20 degrees, 30 degrees, 40 degrees. In Shandong, Q235B is sufficient.
Check the local average monthly minimum temperature, and then look up the lower temperature limit for the piping material (it seems that 20# material reaches 0 degrees). Does this have anything to do with galvanizing?
