    anyway i have problem with eye washers and safety showers

    they are used in outdoor area the water pipe work gets very very hot

    if someone was use safety shower eye wash if an emergency they would

    get very burnt by hot water in pipe work

    the temp here in Pilbara area north or perth in western australia

    big mining area

    here is picture of what they look like

    they have a american value on them thermo temperature value

    they start leaking once the temp gets over 40 degs

    the temperature here ranges from over 40 degs to 60degs some days

    can you come up with solution how i cool the water down

    any ideas would be good

        Not a plumber, but you don't seem to be getting many responses.:

        Insulating the above ground piping may help some. To get the temp down in the water, the only thing I can think of is burying the feed pipes deep enough that the soil temp will keep the feed water temp down. If I remember correctly from a visit to Woomera (out near Coober Pedy) when the temps were about 45 to 50, the pipes were buried over a meter. Maybe a few loops in the ground near the emergency station would be enough, but they will have to hold enough water volume to provide a good flush.

        The other side of it is that when working in a past job where these type shower/eye wash combo's were used (using chemical strippers to remove paint from aircraft), we always gave them a few seconds before sticking our face into them, to let the crap clear out of the nozzles. Although they were flushed weekly, rust would still get in the pipes. If the pipes are buried, that would be enough time to get the real hot water out, although kicking the shower on first may be needed in the safety procedures.

        Hope this helps, Mate. Good luck to you.

        Go

        PS. I have an aunt that lives in Perth. Y'all are some right friendly folks to us Yanks, and I for one appreciate that.

            Bazza Gofor is pretty close on the mark with his suggestion on burying the pipes. If you have the facilities you could even make a coil similar looking to what they used to use in the old distillers usiong copper tube. I dont have details on heat transfer through the cross-link poly pipes but maybe you could go to someone at Rehau overseas and ask. Talk to a geoligist, should be one or two hovering around where you are, and get some help with the earth temperature for setting your depth. Good luck.

              Never made it up to Roxby, so never made it to that pub. The pubs in Woomera were enough for me. Once I opened my mouth and they found out I was a Yank, I had to really push it to buy a round!! A couple of pub friends there took me out to a "footy" game. Now I know why they consider NFL (National Football League) players in the US as "sissies" for wearing all that padding. One guy broke his leg and they didn't even stop the game! Aussie rules are tough!
