Do hoses exist that can handle high pressure air (thousands of PSI) yet can be crushed without damaging the hose?

Certainly. It is called Schedule 160 steel pipe.
By definition, "crushing" is considered damage, resulting in plastic yield. This will result in just a few cycles before the hose will fail.
Move the hose, don't run over it.

Ok, replace "crush" with "collapse".
Say the hose is going to be immersed in *really* deep water until the pressure outside the hose exceeds the inside pressure to a degree sufficient to cause it to collapse. Also, say that the cost of the hose is not an issue.
Dear zjoule:
message news:...
Why does it need to be a hose?
The easy answer is that if it is collapsed, it will not perform its intended purpose. It will collapse so that the radius of curvature in (at least) two places is sufficient to support the difference between outside and inside pressure. This will be an increasingly small flow area, forcing the velocity higher for a given volumetric flow rate. Meaning that pressure drops will be higher, and abrasion will be the likely mode of failure.
I'd look for a flexible pipe, or pipe with swivel joints...

Tell us what the application is. What is inside the hose? What size "hose" do you need? And if it carries high pressure on the surface why is the pressure so much lower at depth that it would crush?
There is something missing here.
