Confused about what you are referring to.

After three to four years I see a small wisp of steam and find a small crack running around the pipe right at the base of the flare. It doesn't fail catastrophically and I have just been replacing the whole 18" pipe when this happens.
Flex pipe thread
That was also copper. I haven't used copper much anymore for sometime except for in special cases (Windemere Kettle).
I'm using SS for tubing and here the tube wouldn't actually be of any significant length, the ss flex hose is doing the real flexing.
I've heard some arguments for and against swagelok fittings for steam elsewhere, it's interesting to note that swagelok has a special steam application group for it's customers.
What capacity (I'm assuming you are using the lbs/hr in a calculation) would be acceptable? Are you suggestioning that to use this safety valve would just open up and dump if you opened the valve to start transferring water.
