DOT & ASME Propane Tank Differences

Should I buy a DOT tank or an ASME tank?

Here are the basic differences? 

ASME Tanks.

  • No Recertification period required.
  • Slightly thicker steel.
  • Heavier than a DOT tank of the same capacity.
  • Designed for stationary installation.  Not designed to be moved when holding propane.
  • Design & Standards governed by American Society of Engineers. (ASME).

 

DOT Tanks

  • Recertification period requirements are:  12 Years after Manufacturing, then every 5 Years.
  • Designed for Portable Applications.  Can be transported with propane if done so according to Code.
  • Design & Standards governed by Department of Transportation (DOT).
