There are very light pressure vessels, and tanks that will hold insane pressure..
Pressure Vessels vs. Tanks. A lot of lay people say the difference between a jet engine and a piston engine is just semantics. You and I know that is incorrect. Just like gassing up a jet plane is not correct.
Pressure Vessels are most often designed to ASME VIII. They are designed, tested, and stamped for a Maximum Allowable Working Pressure, generally above 15 psig.
Tanks are designed to hold the static head of the liquid and a few inches of water column pressure (a fraction of a psig). They are entirely different design codes.
Big difference. Again, the lay person intersperses words that they think are fine, but are clearly incorrect.
