• Hydrostatic Testing

  • What is hydrostatic testing?


    A hydrostatic test is a way that pressure vessels, like pipelines, gas cylinders, or fuel tanks, can be tested for strength and leaks. The test involves filling the vessel with a liquid, usually water, and pressurization of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss. Strength is usually tested by measuring permanent deformation of the container. Leaks are better detected when a colouring agent is used in the testing water.

    Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then re-qualified at regular intervals. The testing of pressure vessels for transport and storage of gases is crucial, because these containers can explode if they fail under pressure.

    Our facilities are staffed with factory-trained and Transport Canada certified technicians who have satisfied and maintained specific standards of performance.

    What needs to be hydrostatically tested?

    Fire Extinguishers

    To guarantee the safety of your workers and facility as a whole, make sure that you are aware of how often your hand portable extinguisher needs to be repaired, replaced and/or maintained:

    • Every 5 Years: Hydrostatic test of carbon dioxide, K-Guard and water-type extinguishers (NFPA 10)
    • Every 12 Years: Conduct hydrostatic testing of dry chemical and vaporizing liquid fire extinguishers as required (NFPA 10).

    Self-Contained Breathing Apparatuses (SCBAs)

    Proper preventative maintenance can go a long way to ensuring your equipment continues to perform at its optimum level. Hydrostatic testing guidelines for SCBA and related products include:

    • Every 3 Years: Hydrostatic test all wrapped composite breathing air cylinders (CSA B339-2002)
    • Every 5 Years: Hydrostatic test all aluminum, composite and steel breathing air cylinders (CSA B339-2002)

    Vehicle Fire Suppression Systems

    Many industrial vehicles operate virtually non-stop, 24 hours a day, 7 days a week. They use a host of flammable liquids including lubricating oils, diesel fuels, greases, and hydraulic fluids. Extensive downtime and business interruption can result in an even greater expense as this equipment often takes many months to replace. Ensure you follow regular inspection and maintenance requirements for your vehicle suppression systems, including:

    • Every 5 Years: Hydrostatic test cartridges as required
    • Every 12 Years: Conduct hydrostatic testing of agent cylinders as required (NFPA 17)

     Co2 Beverage Containers

    • Every 5 years: Hydrostatic testing of Co2 bottles
