Re: Question on rules for pressure vessel
Posted: Fri Mar 07, 2014 11:08 am
The tube has an ID of 60mm and a 1.5mm wall thickness. It is 2.66m in length and weighs about 900g. GRP suggested to us that we only use the tube up to 6 bar. We are reinforcing the tube ourselves to meet our pressure requirements.[/quote]
If it was not intended for high pressure that sounds fine. WRA2 needs to give it the final say but if you are reinforcing it yourselves, then it seems fine. I'm surprised GRP says to use it only to 6 bars. I wonder how much USWR's pressure vessel weighed. This might sound off the wall, but in my opinion a tube of T-12 would be lighter than the tube your buying and it can already hold 6 bars also. You would probably do well to use than and then just reinforce it because there is no point in getting two pipes of the same strength and reinforcing the heavier one and using it. I could be missing something so let me know if this is right.
