Propane recertification is due 12 years after the original manufacturer date and every 10, 7 or 5 years depending on the type of test preformed. A full hydrostatic test, by use of the direct expansion method, is 10 years. A modified hydrostatic test, by use of the water jacket method, is 7 years, and a visual test is 5 years. Other low pressure cylinders are required to be tested on a periodic basis, typically every 5 years.

The following services are provided for low pressure cylinders:

  1. External visual inspection
  2. Internal inspection
  3. External cleaning (shot blasting a full range of cylinders from 20# to one ton)
