jeremyb;11934 said:Just like using paint materials, its all in the application. I hear guys all the time say they have this problem or that problem but anytime i've run pvc for air, i've never had a problem.
dont even get me started on osha, dhec, epa. Had an inspector come in for the yearly inspection...was new and wasnt the original inspector. Had to explain how the paint booth works and what filters were what? Amazing...but did find out that they guys arent subject to just bodyshops...they have 1 person that does EVERYTHING from bodyshops to checking out calls of people burning trash,leaves,etc.. Typical goverment...wastes 3 hours of my day. i should get some stimulus for that time loss right!?!?!?! I'll mention it in my taxes...i'm sure they will understand!
Bob Heine;11969 said:Only reason I chose galvanized was the heat conductivity issue. Thermal conductivity for copper is 400, aluminum is 250, steel or galvanized is 42 and PVC is 0.19. Fifty feet of galvanized 1/2" pipe removes about a cup of water per hour from my system. Galvanized won out over copper on price, even though it's only 1/10th as heat conductive as copper. I seem to recall that Shine and several others have refrigeration coolers so the cooling effect from the pipe is irrelevant for those systems.
