    Not saying it couldn't happen -- a stray piece of thread tape or something could get in there. But otherwise -- there's nothing in the steam which would do it.

    We've had one or two in the past 15 years on the couple thousand orifice plates we have installed.

    What is the device mounted on top of the pipe in the pic? That's not where a trap or orifice usually goes................

    @mikedo. Don't know the circumstances but good for you. Value is not cheap. And there is no crime in making a respectable profit.
