GREATTTTTTT STUFFFFFF!!!!!! Thanks ever so much and thanks to the U.K. ...

I will read this thoroughly later tonight but some points I got from a 2 min scan...

1) PSVs that chatter beat the hell out of the system they are part of therefore "ANCHORING" near to them is essential if the possibilty of chatter is pressent... Having seen steam systems do this I can tell you its quite alarming.

2)Rupture discs burst reallly fast.
