After the burn-through alert on lagged systems awhile back, I lagged only to
within 6" of the head, but the bends still look in pretty poor shape after 50
hrs. running. They are not actually burned through but the amount of flaking
makes me think they probably will soon. So perhaps we will all need
stainless bends ! I wonder what was on the prototypes ?
