TC# on Flatlines

[NewMagMan21]

Why would anyone be interested in the TC number on a flatline tank?

I would answer your question with another. Why someone would need a DOT certification on an HPA tank?


TC stand for Transport Canada just as DOT stand for Department Of Transport. ANy pressure rated container must have a certification number from one of these agency (depending on which country you live). We, canadians and quebecers, need tanks with TC certification. As most if not all pressure vessels are built in USA then they all encounter DOT specs but a few are produced to meet both DOT and TC specs to be sold to canadians.
