Hydrostatic Testing

Hydrostatic Testing: Safe. Compliant. Reliable.

Gas cylinders are designed to safely contain high-pressure gases, but over time, wear, corrosion, stress, and damage can compromise their structural integrity. Hydrostatic testing is a certified inspection process used to verify that cylinders remain safe for continued use.

At Analgesic Services Inc., we provide professional hydrostatic testing services to help customers maintain safe, compliant, and reliable cylinders across a wide range of industries and applications. Hydrostatic testing services are available through our California and Colorado locations.

 

What Is Hydrostatic Testing?

Hydrostatic testing is a safety inspection used to evaluate the strength and condition of a gas cylinder. This test must be performed every 5-10 years.

During testing:

  • Cylinders are visually inspected for dents, corrosion, wear, or damage
  • Cylinders are filled with water for safe testing
  • Pressure is applied above normal operating levels
  • Technicians measure how the cylinder expands and returns to shape

If a cylinder shows leakage, cracking, weakness, permanent expansion, or failed elastic recovery it is immediately removed from service.

 

Why Hydrostatic Testing Matters

Protects Safety - Gas cylinders operate under extremely high pressure. Routine testing helps protect employees, patients, customers, and facilities by ensuring cylinders remain safe to use.

Detects Hidden Problems - Hydrostatic testing can identify internal corrosion, metal fatigue, and structural damage before they lead to failure.

Supports Compliance - Routine testing helps facilities stay compliant with DOT, CGA, and NFPA requirements while remaining inspection-ready.

Reduces Downtime - Proactive testing helps prevent unexpected cylinder failures, operational interruptions, and emergency replacements.

Extends Cylinder Life - Properly maintained cylinders that pass testing can safely remain in service longer.
