5-Year Tank Inspection & Hydrostatic Testing
A five-year tank inspection is the most thorough certification cycle your tank truck undergoes, combining hydrostatic testing, internal visual tank inspection, and tank thickness testing into one full recertification. As a B620 certified facility with decades of hands-on experience, we’ve performed this inspection on petroleum, propane, chemical, and food grade units across Canada since 1975. Book your B620 five-year inspection below and keep your unit compliant for another five years.
What Is a 5-Year Tank Inspection?
Every cargo tank operating under CSA B620 must undergo a five-year B620 tank inspection Canada regulators require, on top of its annual 1-year inspection. Unlike the yearly check, this cycle tests the tank itself, not just its fittings and safety equipment. It includes an internal visual and pressure test to confirm the tank shell hasn’t thinned, cracked, or corroded beyond safe limits, plus documentation proving the unit is fit to keep hauling for another five years.
What's Included in Our 5-Year Inspection
Our 5-year inspection covers every critical check required under CSA B620:
-
Internal Visual Tank Inspection
We open and inspect the tank interior for corrosion, pitting, cracking, or product buildup that could compromise the shell. -
Tank Thickness Testing
We ultrasonically test wall thickness at multiple points, part of every tank truck thickness testing pass, to confirm the metal still meets minimum requirements. -
Hydrostatic Testing
We perform a full tanker hydrostatic test, pressurizing the tank with water to confirm it holds at rated pressure without leaking or deforming. -
Tank Pressure Test
For pressure-rated units, we run an additional tank truck pressure test to verify relief valves and fittings perform under load. -
Documentation & Recertification
Every result is logged and stamped, completing your tank recertification and updating your unit's inspection record.
Hydrostatic Testing for TC406 Tanks
Every fuel and petroleum unit we inspect undergoes a hydrostatic test for TC406 tank compliance, confirming the tank still meets its original design pressure five years after certification. This step catches slow degradation that a visual inspection alone can miss, which is why it’s required under both TC406 and B620 standards.
Pressure Vessel Inspection & Repair
Some units, particularly propane and compressed gas tankers, also fall under pressure vessel inspection requirements. If we find an issue during testing, from a thinned shell to a failed weld, our in-house team performs pressure vessel repair on site, so your unit doesn’t have to leave our shop to get back to certified.

FAQ
Frequently Asked Questions
What is a five-year tank inspection?
A five-year tank inspection is a full B620 recertification cycle that includes internal visual inspection, thickness testing, and hydrostatic testing.
What is hydrostatic testing?
Hydrostatic testing pressurizes a tank with water to its rated pressure, confirming the shell holds without leaking, cracking, or deforming.
How is a 5-year inspection different from a 1-year inspection?
The 1-year inspection checks fittings and safety equipment, while the 5-year cycle adds internal visual inspection, thickness testing, and a full pressure test.
What happens if my tank fails inspection?
If your tank fails, our in-house team can often complete the necessary repair or structural work on-site, then retest before recertifying the unit.
Do TC406 tanks require hydrostatic testing?
Yes, every unit undergoes a hydrostatic test for TC406 tank compliance to confirm it still meets its original design pressure after five years.
Do you offer 5-year inspections in Calgary?
Yes, we provide tank truck hydrostatic testing Calgary fleets rely on, along with nationwide inspection and recertification service across Canada.
