Hydraulic Accumulator Testing & Inspection
Northland pressure-tests, inspects, and certifies hydraulic accumulators so you can return them to service safely and with documentation. Accumulators are pressure vessels that store energy under high-pressure nitrogen, so regular testing and inspection aren’t just good practice — on many Alberta job sites they’re expected. We test and certify bladder, piston and diaphragm units of every major brand.
Pressure testing & leak inspection
We pressure-test accumulators to confirm they hold to spec and inspect for gas and fluid leaks, shell integrity and valve condition. Testing verifies the unit is safe and performing before it goes back into a live hydraulic system.
● Nitrogen pre-charge verification
● Pressure / hold testing
● Leak inspection (gas and hydraulic)
● Shell, port and valve inspection
Certification & re-certification
We certify accumulators after testing and re-certify units already in service, with documentation for your maintenance and safety records. If you run a periodic inspection program, we can test and re-certify your accumulators on a schedule.
Accumulators are pressure vessels
Because an accumulator holds significant energy under pressure, it’s treated as a pressure vessel — which is why testing, inspection and proper documentation matter, especially on regulated sites. Northland tests, inspects and certifies accumulators to the standards required on regulated Alberta sites and provides the documentation your safety program needs.
Frequently Asked Questions
-
Accumulators are pressure vessels, so periodic testing and inspection are strongly recommended and are often required on regulated sites. Testing confirms the unit holds pressure, is leak-free, and is safe to return to service.
-
Inspection frequency depends on the application, duty cycle and site requirements. Many operations inspect and re-certify on a set schedule; we can help you set one and carry it out.
-
Yes — we test, inspect and re-certify in-service accumulators and provide documentation for your records.
-
Yes — pressure equipment in Alberta is regulated and accumulators are pressure vessels. We test, inspect and certify accumulators to the required standards and provide documentation for your records.
