Steam Blow
(OP)
Can someone explain the purpose of the target inserter that are used during steam blow? Are there any specific type of material to be used as a target inserter for steam blow?

RE: Steam Blow
As far as the target material I've about every thing used. We tend to use percale, bed sheets.
RE: Steam Blow
I was in the field on an assignment a few years ago (20 or so) and asked to assist with the design of some pipe restraints to be used for the steam blow. This was a new plant and they blew down each steam line a number of times to remove the trash and debris inside the piping. Once they thought the line might be clean they would insert the target. I remember it being a 1 inch square bar polished to a mirror finish. I don't remember if it was stainless or carbon steel. Any scale or debris in the line would cause pitting on the side of the bar facing against the flow during the blow. If the pipe was still dirty, they would blow it down a few more times and reinsert the target bar again, rotated for an unpitted side to face the flow. They kept repeating this until the line was clean.
The steam lines fed a lot of turbine drivers on pumps. It was actually the turbine vender field representative that was supervising the steam blows.
My most vivid memory of this was the incredible noise. Everybody in the plant needs to be wearing ear plugs during the blows as well as stay out of the way, especially downstream of the blow.

Thanks again.
RE: Steam Blow
So, my experience that I related above was the 'high-pressure exhaustive' blow.

Yep......much sexier and a lot more fun than the continuous low-rumble water-quenched non-exciting kind.
