I'm attempting to design a hypothetical suit that would protect the wearer from close proximity to a steam explosion, in addition to high radiant heat for prolonged periods. The steam would be at 125psi and 350F in pipes, although in the event of direct steam exposure the pressure would have to have dropped a lot due to pipe rupture.

I'm imaging something along the lines of NOMEX coveralls and hood for conductive heat protection with an out aluminized mylar shell as a vapor barrier and radiant heat shield. The suit would have an "escape SCBA" in the event of pressurized steam exposure, which would buy the user enough time to escape from the source.

The visor would probably be something along the lines of a cellulose-acetate faceshield with regular mirror tint window film applied for low emissivity.

The general configuration would be similar to a fire prox suit (pictured)

Any more brainstorming on this?

Stopped reading right there.

Also the suit would obviously have to either seal rather well, or else use an open circuit SCBA.

Now THIS is autism.

Actually, this is a not so hypothetical plan to explore steam tunnels...

>implying autists can ever be inventive

OP, are you sure the psi is going to be 125? That's insanely high.

Sort of a worst case scenario for the actual steam lines.

The suit will never see anything close to that unless you sit on a steam line while it explodes.

>>4414165
That's still an impossible pressure. You want a UV, not a manned suit.

>> No.4414179

>>4414171
Yes, but there is a big difference between what is in the steam lines, and what a reasonable worst case for someone even close to the steam lines will see as far as pressure. You don't really hear about the blast from steam explosions injuring/killing people, it is the heat.

>> No.4414185

>>4414179
I'm not saying it's the pressure that would kill you. But the suit would not be able to withstand that kind of pressure unless it was extremely, extremely well designed. I can't do it, and I doubt you can.

>> No.4414188

>>4414185
Again, I really don't see the suit getting anywhere near 125psi. The pressure of a steam line is going to drop enormously in the event of rupture, it won't just suddenly make the entire tunnel 125psi.

>> No.4414192

So you're willing to just ignore the risk? Very well, make sure you tell anyone who wears it to stay away. I don't really want to give advice, both because I might be wrong, and I don't know what you're going to do with it
