PRESSURE TESTING

We offer clients pressure testing services for pipelines and pressure vessels in the following disciplines:

  • Hydrostatic

    This involves using water or the normal line
    product as the test medium, normally at a
    pressure of 1½ times working pressure, for
    a specific hold period.

    Test Certification is issued for tests that meet
    the criteria and a Test Failure Notification is
    issued for pipelines not meeting the required
    standard.

  • Pneumatic

    This is only used on certificated pipelines where water or line product is unacceptable for Environmental or Health & Safety reasons, such as creating an exothermic reaction.

    Nitrogen Gas is the normal test medium used and test pressure is normally restricted to 1.1 times the working pressure.
  • Vacuum

    This kind of test is usually specific to the testing
    of Floating Fuel Transfer Hoses and as such it is
    normally performed after a Hydrostatic Test to
    ensure the integrity of the internal hose lining.

    This type of test is carried out in accordance with
    the OCIMF Guidelines which includes electrical
    continuity / resistance measurement parameters
    and consequently specific test certification applies.
