Can anyone tell me what tank would be safer? As I worked manufacturing "Catalina" scuba tanks over 13 years ago.These tanks were made from #6061 Alum./1/2 in. thick.
The trouble we would face was not a bad valve. But bad materal from the foundry.
Some tanks would show no sign of hair line cracks inside of walls of cylinder,and some did show slight cracks.Yet the tank would still pass visual scope camera inspection. I guess after testing under pressure of 3000/+psi....If it didn't blow up under water in the safety tank it passed...In all.....For all practical reasons...
But when a tank explodes,out in the field of sport diving,The first thing that the media comes to blame is a bad valve....
yep not a tank that had bad materal to begin with from the manufacture.
That might put ,LUXFER,SHERWOOD,&CATALINA CYLINDERS out of business.....
