SCBA Cylinder Hydrostatic Testing

SCBA Cylinder Hydrostatic Testing
Quote:
All SCBA cylinders require periodic hydrostatic testing as required by 49 CFR 180.205.
The frequency of the maintenance depends upon the cylinder material.
  • Steel cylinders should be tested every five years and have an indefinite service life until they fail a hydro test
  • Aluminum cylinders (not including hoop-wrapped) should be tested every five years and have an indefinite service life until they fail a hydro test
  • Hoop-wrapped cylinders should be tested every three years and have a 15-year service life.
  • Fully wrapped fiberglass cylinders should be tested every three years and have a 15-year service life.
  • Fully wrapped Kevlar cylinders should be tested every three years and have a 15-year service life.
  • Fully wrapped carbon fiber cylinders should be tested every five years and have a 15-year service life.
Fiberglass / Composite Tank Inspection Services
Quote:
A hydrostatic test of a vessel alone just reveals its ability to contain the liquid product at that exact moment in time.
An inspection, employing such industry techniques as interior/exterior visual and instrument inspections to reveal spidering,
disbondment, abrasion wear, emulsification, Barcol hardness, floor stress cracking, shell distortion and ultraviolet degradation,
is an integral part of an overall survey.
A fiberglass tank may pass a hydrostatic test today, but that doesn't necessarily mean it will pass three months from now.
