Small 0.6-1 liter bottle rated to 100psi (6.9bar) 1

[ESTinker]

Anyone know of a company that makes a bottle either aluminum or stainless 0.6-1 liter that is rated up 100psi(6.9bar) of compressed air?

Everything out there is either rated with no pressure (standard cheap water bottles) or overkill at 1000+psi(69bar) (expensive scuba tanks or paintball cylinders), something in between the cheap water bottle and scuba tank would be nice.

Try to Google online with the "air tank" and find the tank manufacturer and size to meet what you are looking for.
Good luck.

The issue with very small tanks, is that by the time you have made something robust and manufacturable out of metal, they are typically good for a high pressure which is why you are having issues find one that is only rated for 100 psi.

Perhaps easier to search for metal bottle and go from there. You will find the cheap ones, and have to check out the quality.

Swagelok sample bombs are probably overrated/-kill.
Hidracar makes simple, cheap and good pulsation dampeners; can you use such one instead? Oh by the way, just noticed on their site they also have simple small air tanks.

Can you go with a simple black iron or stainless steel threaded pipe and two end caps? Small dia needs a longer pipe, shorter pipe length requires a slightly larger dia pipe.

Looks ugly, but can use a nipple in one end cap for the attachment.

I wanted it to be as light as possible so staying away from steel and pipes.

I guess why can't I just use an aluminum or stainless water bottle and do hydrostatic test to 300psi and if no leaks then it should be good to go. Correct me if I'm wrong, pressure vessels are suppose to withstand 3x the rated pressure, is this good enough of a test? I don't want to get into any safety concerns which is why I don't want to use plastic bottles.

Wish there is a way to get wall thickness of these to figure out the hoop stress, these should be able to withstand 300psi.

They are cheap. Buy one, section it. Then, if you only knew exactly what it is made of...

The problem with sloppy work is that the supply FAR EXCEEDS the demand

1. What’s the purpose or application?
2. Three times rated pressure; no.

In many small bottles the closure is the real issue.
If I was looking for testing I would want to know burst pressures and the results of multiple pressure cycles.

I'm helping a friend building a light weight portable air and water spray system with short bursts (1-2sec) of 70-100psi air for removing surface dirt/dust for remote sites archaeological purposes. I want to keep the weight down as much as possible.

Catalina cylinders do a range of low pressure bottles, including some in the sort of size range you're talking about.

They look a bit like the aluminium water bottles you posted pictures of, but the neck threads are much longer and better formed. We did a series of test bursts on some of the 600 psi bottles a few years ago and they were impressively consistent, failing at very close to 50 bar.

There are lots of dust-off products on the market that use a liquefied propellant. Compressed air loses pressure linearly with use. The liquefied propellants contain about two orders of magnitude more gas and maintain pressure until empty. This is a case of reinventing an inferior wheel.

Maybe a small air pump would be better?

The issue with small containers is the hemispherical head.

Would probably need about 3 suitcases of air cans (3-4 weeks worth), it will hundreds of miles from any civilization but they will have a generator to supply power. I plan on filling the bottle with water half way and using a dental syringe to release air, water, or both (air/water mist) from the bottle.

Consult with fire extinguisher fabricator.

Try having at this sort of thing

The CO2 might not last long, but if the bottles will stand a certain number of re-fills, they might fit your needs.

Pressure seems to be about right and cycle stuff is very weight conscious.

I think the main point of this is to give a big blast of air for reseating tubeless bicycle tires. I think some other similar products are out there, also some floor pumps with a built in tank for the same purpose.

 

[Compositepro]

Or just use a suitable bicycle pump with a nozzle to blow dust off.

You might look at rechargeable spray bottles like this:

There may be third world knock offs at a lower price.
