"If you don't respect the captain, you don't respect the sea." OK (just couldn't let that one get by)

Seriously, Tim is right. I have the ability to fill to 5000psi, my pressure relief is currently set at 3200psi. I see all the tanks that the customers have marked "3000" that are 2400psi lp steels. I train my crew to observe the tank rating. We fill steel tanks 100 to 200 psi high "hot". That allows for the tank to cool to rated pressure as the rate of expansion in steel tanks is greater. The aluminums are a different story, rated pressure only. One tip on aluminum tanks. Keep the neck wet when you fill them. If they bubble under pressure, let the customer know. They could have a potential problem.
