put down the owsi god handbook and step away from the advanced video....
No tank exploded in cave country during that time. Fact.
Some tanks are more 'dangerous' to fill beyond their 'stamped' pressures than others..notice I did not say their safe pressure.
I have filled a few tanks in my time and here are rules that make sense:
Do not over fill steel 72-s ever! these are in my mind the most dangerous ones out there for this practice. These have historically cost the most insidious of injuries and are overlooked when they blow at 1800 psi.
Alum 80's are a mixed bag but a 10% overfill is acceptable.
now those lp tanks 104's etc are engineered to do 10000 cycles (that's right 10K cycles) at 4000 psi. Here (usa) they are stamped 2400. How many of you guys/gals have had a single tank cycled even 1/3 as much?
3500 is reasonable in those tanks
