WOW!
That sounds very dangerous to me Peter.
Are you sure copper systems are designed to operate at those pressures.
Personally I would not think so!
But then again I have been wrong before!
Grizzly
CO2 condensers must withstands these pressures
That what I use for years now for brazing copper to copper for a gas company.
Its tested at 300 bar. The pipes have thick wall though, 1.5 mm on 6 mm pipe and 4 mm on 24 mm pipe.Attachment 15331
Peter,
If everything in circuit is rated to that pressure then should be ok.
A lot of stored energy though if something does go wrong could be catastrophic.
If hydraulic system they would call it low pressures probably!

They give here much lower figures once you soldered something, this was the reason for my question.
Straight tubes is not a problem but joining tubes together or soldering an elbow...
Ranger, we need for an application an OEM made condenser (truck vending) and we want to use CO2 for this. The condenser is the part most prone to explode.Quote:

In your link page 75, bottom of chart, it indicates silver soldered joint or material with 1100 deg F or above melting point, same pressure rating as annealed tube.
If condenser has joints soldered then they would be annealed, wouldn't they?
Obviously it is correct to research properly for pressures we are not familiar with.
Is it something you could also do, pressure test a small sample in a safe way to get confidence in it?
This was in link for refrigeration

Hi,Peter
as always ... you ask a difficult question ... must say ... have no experience ... but ...Quote:

my thoughts ...
why not use SS condenser certified for high pressures ... no headache about safety ... OK, probably not cheap either, but safety is priceless ...
