312-11 - High Pressure Cylinder Hydrostatic Retesting Service

Professional High-Pressure Cylinder Retesting

At Josef Gas, safety is our top priority. Our High Pressure Cylinder Retest Service ensures that your customer-owned cylinders meet all necessary regulatory standards for continued use. High-pressure cylinders, used for gases such as Oxygen, Argon, Nitrogen, Helium, and various welding mixes, are subject to extreme internal forces. Over time, the metal casing can suffer from fatigue, corrosion, or external damage that compromises its ability to hold pressure safely. Regulatory bodies like Transport Canada and the DOT require these cylinders to be periodically tested—typically every 5 or 10 years—to verify their structural integrity.

Our retesting process is thorough and conducted by certified technicians. It begins with a meticulous visual inspection to identify any external gouges, cuts, or excessive rust. The cylinder is then subjected to a hydrostatic test, where it is pressurized with water to a level significantly higher than its service pressure. This measures the elasticity of the metal and ensures it returns to its original shape within allowed tolerances. Once the cylinder passes, it is dried, inspected internally, and stamped with the new test date, certifying it for continued service. Trust Josef Gas to keep your equipment compliant and your workplace safe.
