safe distance from a steam pipe rupture
safe distance from a steam pipe rupture
(OP)
In light of the recent fatalities at the japenese nuclear plant caused by the rupture of high pressure steam pipe which caused fatal burns, could someone tell me how I could calculate what safe distance a person needs to be away from the pipe in case of rupture.
My steam pipes carry 10barg saturated steam. I've been told that a temperature of 70C is sufficient to cause fatal burns.

Some concerns are
1)The failed pipe may whip.
2) In addition to temperature, Over time the steam may displace the atmosphere reducing the oxygen for breathing.
3)A steam jet may hit other essential equipment.
4)The room or area of the failure may be subjected to a pressure rise causing wall damage.

refer to responses in chemical plant design forum.

Pipes shouldn't rupture, perhaps a joint may leak. 10 bar is not a lot of pressure.
I would suggest simply making sure the right materials are used and tested. Install dual safety valves and discharge to a safe place.
Where personnel are at risk from damaging tyhe pipework (ie fork lifts etc) then limiters should be fitted together with guards around the susceptible pipe.
