  • Woman injured when pipe burst at Taj dies

    This happened last month in Atlantic City and was published in the Atlantic City Press on Saturday, May 27, 2006


    ATLANTIC CITY — One of the women who was in a room at the Trump Taj Mahal Casino when a water pipe burst died Friday at a Philadelphia hospital, a casino spokeswoman confirmed.

    The full story as printed is here:
    http://pressofatlanticcity-proxy.nan...-6244016c.html

    -----------------------
    I heard (second hand so not very reliable intel) that this facility ran their HW mains at 180F and 275 PSIG. Also that 95/5 solder was used on the copper lines in this system. I did not work this job back when it was being built (~1990 IIRC). It is one of the few casinos that I have never worked in, so I don't know anything first hand.

    My question or concern is operating a system with that high a pressure and temperature that is joined with soft solder. The article does not say if a solder joint is what blew out or the pipe wall. But it got me wondering if there exists a table or chart anywhere which tells you the yield strength and/or safe working temperature at various pressures for different composition solders. I can't recall sever seeing anything like that, if I did my brain has been wiped clean and reformatted a couple times over the past 50 years so I have lost track of it.

    Anyone ever run into this before? Does your plumbing or mechanical code include any limitations regarding operating temperature and pressure?

    I haven't read this through, but it appears to address electronic solders for the most part.

      If the actual copper tubing burst, I thing there must have been some defects, I think it must be more likely the joints burst. But that pre-supposes they were using type K for that temp and pressure.

      I'll look through my library tomarrow for a chart.

        bob, very interesting links. i'll let you know what i find as soon as i finish my phd degree. might be another 10 years

        i thought all we needed to know was to cut, clean, flux, heat, solder & wipe

          Rick, that clean,flux,solder,wipe is already the advanced degree. The standard for journeymen is

          hot water is on the left
          payday's on friday
          Everything else is advanced.

            OK, here's what I found. I think I saw this some time ago but I just couldn't remember where. I asked a friend of mine if he knew of a table and he sent me this link.

              bob d. this is more like it. i actually can relate to this new table. the others were way to high tech for me.

              now if i have a few hours to review all 56 pages. i did scan through some of the tables and was amazed to see some of the pressure curves as the temperature and type of solder was varied.

              very interesting.

                Rick,That is pretty much the same CDA handbook which has been around since William Coffey's days. It is full of very interesting information. I would say William Coffey was probably one of the most intimidating Experts I have ever had to go against. His death was a real loss to the copper piping industries.
