They hard mounted the system - and that was their first mistake - and I think it was that initial expansion and contraction with it being hard mounted that set up the hairline cracks... It's since been re hung allowing for some movement.

My system "grows" at least ONE INCH in length... And Tim came up with a masterful redesign of the hanger to accommodate that.

Hmm surprised they didnt do a fusion "root" pass then a cap..

/weld inspection theory.
