mega press

I just read that Viega MegaPress is rated for low pressure steam. We repair steam and return lines on a daily basis. What do you guys think about pressing with black pipe on steam?

    I hope

     you do make it:) How about returns? On steam, we have problems with old 2" steam risers leaking and no access  to fittings up or down the line. It builds character threading an existing 2" steam riser in an apartment bathroom with a 700.

    Big Question - How long do EPDM Gaskets last?

    I guess it all depends on what you consider a reasonable life expectancy of steam system piping. ( I would be really interested in what life expectancy figure Viega uses.) The live expectancy of EPDM is usually stated as a minimum of "20 years" and the figure of "25 years" is sort of a rubber/plastic industry standard. (Other rubbers like silicone can go longer than this). EPDM and similar products have only been in use for around 50 years so they have a long way to go just to match the known life expectancy of threaded black pipe used for steam systems, many of which are still in use now and going strong after a hundred years.

    I can see the definite benefits in labor saving for using this system and with a reasonable service life, probably the worst thing that could happen is that you would belong to a new group, " those  !*#^%%*!# Dead Men that used EPDM Press fittings!"  and be cursed every day, 30 years from now :)
