No, there's a difference. A valve break means a steam leak. A pipe break means a steam geyser! What you see in this (above) video is the result of a valve problem.
Not exactly. What happened in the video is that a VALVE succumbed to the incredible heat and pressure inherent in a system that puts 475-degree steam at high pressure through cast-iron pipes. Cold rainwater flowed today into proximity with a cast-iron steampipe, laid in 1924.
Grand Central (search TourguideStan) is a block away. In 6 hours, 300,000 commuters' trains are going to arrive.
Stan, the brits and aussie news reported that the police were commenting on a transformer vault...an exloding transformer could cause the pipes to rupture. Theis is no way for rainwater to impact on a searing hot steam line, but a broken water main could flood the concrete vault, causing super-heated steam to cool suddenly and rupture the pipe. Was there any reports of sewage leaks?
There is none that I'm aware of, though one news report said that crews had worked on the steam pipe in May and June, and that more work was slated for July. Check that out on NY1 dot com; it aired Friday.
Now you can give us a tour of the Chrysler building! Have you watched the movie Volcano? That is what the steam venting looks like on the videos that are already on youtube!
i live near philly and they let the steam into the air and thanks for making the video i wanted to know what it was!

BTW I was wrong on steam-stack temp. The video has me saying it's 475F. It's actually only 375F. My bad.

wow....we don't have that here in alabama

All due respect, Alabama really doesn't need a steam system to heat 2000 multistory buildings.

So basically one of these valves broke on the east side causing that huge explosion?

468nam, you're definitely New York...definitely a nut job!
Nice video...now I wonder how they're going to get a steam vent that big to cover the leak at grand central?!

They're going to have to shunt the pressure away, from farther up the line. Then cap that pipe. Then lay in new pipe. This will take days.
Boy, did you see how fast the steam came out of there?
It's under incredible pressure.

I'll do the Chrysler Building for you if I can. They have a policy of charging money for use of its image.
