Steam Hammer due to valve opening

Steam Hammer due to valve opening

Steam Hammer due to valve opening

(OP)
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

RE: Steam Hammer due to valve opening

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.
