Not to jump on your thread but ....
That's actually a awesome idea, I was thinkin the same thing.
Well actually I was talkin with a union brother and we came up with it together, we use these in the oil and gas industry coming of headers, usually 18+ " in diameter , these expansion bellows.
But your suggestion , who would supply those, you have a contact with 300 series stainless in a 3 " scenario

flex joints are readily available just about anywhere but the bellows in mind ( picture below ) are just a bit harder to find locally. since they are normally about $100 a pop I want to get to see it before I buy.

I already have the flex joints in there but those well not stretch or compress as much they're more for vibration. these bellows are more durable and suitable for this application.

What you have will do the job as they also help with expansion and vibration issues....


Read the description on this "flex" joint and they say that the bellows style creates turbulence.... and I'd agree. Whether it's critical for your application is a different issue.


3" versions.

Vibrant does NOT carry flex bellows in 3"

These guys supply the BELLOWS style with an internal slip joint for smoothness....
