Hydrostatic tests provide important safety assurances for pressurized vessels where catastrophic failure could result in serious injury or death. Ensuring vessels and their components have the structural integrity to safely withstand their maximum working pressure, hydrostatic testing helps to detect leaks or other defects in either build or materials that pose significant risk during vessel service life.

Commonly conducted across various industries, hydrostatic testing is critically important to the following:

• Oil & Gas: Pipelines, storage tanks and other transportation vessels

• Aerospace: Aircraft fuel tanks, pressure vessels and high pressure components

• Chemical: Tanks, reactors and chemical processing equipment

• Transportation: Gas cylinders and hazardous material containers

The frequency by which hydrostatic tests are conducted is determined by applicable regulations. As a general standard, hydrostatic testing is mandated every 5 to 10 years, although this range may fall short of what is required for vessels subject to intensive work cycles that regularly maximize working pressure.

Components Required for Hydrostatic Testing

The key components necessary to conduct a hydrostatic test are:

• A pressure vessel or component to be tested: This is the item that will be subjected to the hydrostatic pressure.

• A liquid: The liquid used for the hydrostatic test is typically water, but other liquids may be used depending on the specific requirements of the test.

• A hydrostatic test pump: This is the equipment used to apply the hydrostatic pressure to the pressure vessel or component.

• A pressure gauge: This is used to measure the pressure of the liquid in the pressure vessel or component during the test.

• A pressure relief valve: This is used to prevent the pressure in the pressure vessel or component from exceeding the safe working pressure.

• A means of monitoring for leaks: This may include visual inspection, dye penetrant testing, or ultrasonic testing.

Ensuring proper safety and equipment calibration procedures are followed prior to performing hydrostatic testing is critical to accident prevention and result accuracy.

Conducting a Hydrostatic Test

After proper safety and preparation standards have been accounted for, equipment can be connected to the vessel and test procedures can commence.

An example of a typical hydrostatic test procedure is as follows:

 

 

Running the test is straightforward, once the pump is connected to the system and is operating, water (or another test liquid) in the vessel is pressurized beyond typical operating pressure, typically 150% of designed working pressure, and monitored.

During the duration of the testing period, which is dependent on application, pressure is measured closely for drops that would indicate faults in the vessel. In some cases, this may be more obviously observed by liquids leaking from the vessel. The use of dyes in the test liquid is a common practice to distinguish test liquids, particularly if the hydrostatic test is performed on a coded vessel that is outdoors rather than being newly manufactured.

Once the determined test period has elapsed and no leaks are found, the test is complete. The system is slowly depressurized, liquid is drained and previous component removed for the sake of testing are reconnected.

Results are validated by the present pressure equipment inspector and the vessel is stamped to indicate a “pass” result. The stamped information will include the date of the successful test, identification of the test facility, as well as identifiers detailing design standards, manufacturer name and date, as well as the serial number for the vessel.

Selecting the Right Hydrostatic Test Pump

With sustained pressurization key to performing a successful hydrostatic test, selecting the right pump for testing applications is paramount to meeting the parameters necessary to merit a factual end result.
