This is ducting, not for anything hotter than your dryer vent. Will work well for residential ducting.

What is the highest temperature that this can withstand? I am looking at hooking it to an industrial ink dryer where the temp can be continuous 550+

For that application, I wouldn't even advise Type B double-wall gas vent pipe. Contact Selkirk (by Duravent) or do a web search for the website, and take a look at their all stainless steel wood stove (et cetera) chimney/exhaust pipe. It's multiple-walled, HEAVY duty pipe that is rated for continuous high temperature applications, and might just outlive you. Another brand is Metal-Fab Type L Vent Pipe for Oil Burning Appliances. Unlike the Selkirk stuff, I do not have any personal experience with this brand, but it's also rated for the temperatures you're working with (570F constant, with a 10-minute 1,700F safety "over-fire"). These types/brands of products not only hold up well to continuous high-temperature flow, they also (when installed/used properly) help protect the surrounding materials from the heat.

Can the hose withstand negative 30 degree temperatures? I would like to have this go out the window.

I don't see it being a problem at all. It should be able to be pretty much water resistant to a point. Just remember if you start moving it back and forth and water is allowed to freeze you can rip it apart.

Can you connect this to another length of ducting if you need to extend it?

Yes it’s just like any other duct should work great 😊
