Steam Hammer due to valve opening

[strainstress]

Hi,

I am trying to figure out the effect of fast opening of valve containing high pressure steam (1140 psi) on one side to a large condenser coil tubes. The tube is U shaped 1.5" OD, SST. How do I calculate the hammering loads. Does the fast opening of valve has any significant effect on the system ?

Any reference to literature addressing this phenomenon would be greatly appreciated. I have a lot of literature on valve opening (Jourowsky Euqation). But the valve opening phenomenon has not be addressed widely.

Thanks

Steam equipment should always be brought on line gradually, to avoid excessive condensate loads among other things.

Steam hammer is something different, a google search can explain it better than I can here.
