HYDROSTATIC TANK TESTING | Tampa, St. Petersburg, Clearwater, Sarasota, orlando


Hydrostatic testing is a pressure test that verifies a cylinder can safely hold its rated pressure without failure, required periodically for fire extinguishers, SCBA and SCUBA tanks, and other DOT-regulated pressure vessels. Piper uses the Water Jacket method — the most stringent of the three DOT-recognized testing procedures — measuring how much a cylinder expands under pressure and confirming it returns to its original shape once pressure is released.
For fire extinguishers, this test is required by NFPA 10 every twelve years; other cylinder types follow their own DOT-mandated intervals. Every test is documented, and Piper is DOT-certified to test all cylinder types we service.
As part of the Fortis national network, Piper's hydrostatic tank testing expertise is backed by national training standards and technical resources — giving West Central Florida facilities access to the same level of precision engineering as any major market in the country.

NEITHER DOES OUR TESTING STANDARD.
We bring that same fire-safety-grade process to the cylinders that keep other people safe, too: scuba tanks, tested for dive shops throughout Piper's Central and Southwest Florida service area — Tampa Bay to Orlando to Lee County — on a DOT-mandated 5-year cycle; medical oxygen canisters, held to the same rigor as any other life-critical pressure vessel; restaurant CO2 tanks, serving beverage and draft systems across the region; and paintball cylinders and life rafts — smaller cylinders, same non-negotiable standard.

HOW PIPEr's hydrostatic tank testing WORKs
Cylinder Intake
Bring your cylinder to Piper's testing facility, or Piper collects it as part of a scheduled extinguisher or SCBA service visit.
Water Jacket Testing
The cylinder is filled with water, lowered into a test reservoir, and pressurized. Displaced water is measured to determine how much the cylinder expands under pressure — a roughly 30-second computerized process.
Analysis & Grading
The system compares permanent expansion against temporary expansion to grade the cylinder's safety and confirm it passes DOT requirements.
Drying & Return
Cylinders are dried using high-powered steam dryers and returned ready for service, fully documented.

Fortis Family of Brands
Trust is built locally. It lives in the technician who knows your building, knows your local codes, and shows up when something goes wrong at midnight. It lives in the relationship between a fire protection company and the community it has served for decades.
But capability is built at scale. The training standards, the technical resources, the purchasing power, the shared knowledge of a unified national organization — these are the things that make a local provider exceptional rather than merely adequate.
Fortis was built on this belief.
Our network of regionally rooted fire and life safety companies delivers genuine local expertise in every market we serve — technicians who know the regional AHJs, the local codes, and the specific demands of the facilities in their community. Behind each of them stands the full weight of a premier national organization.
You build. You create. You push the world forward.
We protect it all.
