    Pipe size charts for R404 & R407



    Does any one have a pdf of a pipe size chart for quick reference purposes as we used to have R12/22/502 charts?

    Look for Coolpack on your browser. Download it.

    They have a complete package, from piping design to coldroom sizing.

    We ar loocking for the same.
    Experimentally we found that 22 piping can be small for 404 or suva 82, but for capacities of 30 tons loock so mutch bigg. I found a work paper done by Dupont very good, but dont include the nomograph for velocity in 404 0r suva
    We are cheking in Buenos Aires, with Dupont Argentina, for try to obtain this nomograph.
    ¿ some one has the idea if piping for ***** 22 is smaller for 404?.

    I think that this is what you are searching!
    It is from DuPont Suva Refrigerant piping handbook available at their page.
