Anyone know the pressure rating on 22mm tubing and soldered joints and pressure rating on the compression joints?

I have designed a few water heating units using soldered joints. Usually max working pressure of 10 barg. Normal water pressure can get up to 50-100psi.

What you planning on using it for? And it obviously depends if its a swaged compression joint and how tight you have put it on but if its for high pressure solder or braise it, I have seen a 54mm compression cap end blow off at ten bar and if it hit any one it would hav killed them luckily it didn't |

What is it you are trying to do? Steel compression fittings are out there for hydraulics, good for 200bar or more.

Just a quick search on google showed semi hard 22mm copper pipe with a 3mm wall will withstand 51bar (740 psi) |

trying to make pipe bombs or something ? close lol as some of you may know i have a selection of home built air rifles this time i am going to build a 6mm smooth bore ( bb gun) with an auto cycling pneumatic bolt, i have been designing this for years but never managed to get it to load properly due to the solenoid air valves i was controlling it with well i have come across a new ( to me) valve that can simplify the whole process to 1 control valve and a storage chamber to cut a long and boring story short im just looking up cheap and fast options for the chamber but i dont think it will hold up to the pressures i will hopefully be trying it at 
something like this ( the way it fires not looks ) http://www.youtube.com/watch?v=FsY0b_CRWpg...6E2FC7&index=10 Yes i moved to the darkside |

FFS, air rifles and pistons are illegal over here !! Nevermind a machine gun version lol well thats just shit!! bore is not critical once above 10mm ish but... i think im just going to adapt an 88g co2 cartridge there are good for 1000psi easy i will be running regulated co2 on this i think so likely not to see more than 200psi in operation man i wish i had a lathe

it is basically that, much larger valve and a 24 inch barrel all steel and ally, whisper quiet and can group pellets on top of each other @ 25m :) my local range has not long since shut down so dont get to play at longer ranges much anymore

Pistons are legal fortunately. Pistols are not lol Biggest legal thing here without a license is a mechanical BB gun ! and even then, carrying a pistol could get awkward. get some of that CDS tube, there are loads of diameters and it would be more than up to the task 9.85 @ 145mph
