The hydro test is a test that is performed utilizing water and a hydro testing pump. Water is pumped to a set pressure using a hand/engine pump, and the system must be shut down for a while to check for any leaks or failures. If the pressure drops after reaching the required level, there is an issue with the unit.
Hydrostatic testing is a dangerous procedure since it entails applying high pressure to the system, which can cause catastrophic physical harm or property damage if it fails. The following is the vulnerability associated with hydrostatic testing, notwithstanding the fact that it is done under the supervision of a qualified person.
Risks of Hydrostatic testing
- In case of a leak or burst, high-pressure liquid can tear skin or damage internal organs.
- The hose of a pressure test pump can detach and hurt a person close by.
Safety checklist
To prevent such life-threatening accidents, it is important to follow a comprehensive safety checklist. Here we have compiled one for you. Read on.
- Adhere to the permit-to-work procedure and inform engaged workers about any potential dangers.
- Always conduct hydrostatic tests under the guidance of a qualified expert.
- On the specifications, clearly designate the scope of the hydro test and ensure positive isolation of any equipment or pipe that isn't part of the hydrostatic test loop.
- Even if it's new, inspect all test equipment and tools.
- Before the test, check the design pressure of the apparatus, such as the vessel, pipe, and so on of the hydro test pump.
- Verify that all pressure measurement devices and tools are calibrated.
- Every component must have a pressure rating greater than the maximum hydrostatic pressure.
- Check that the safety relief valve is adjusted and calibrated correctly.
- Set at least two pressure gauges in a convenient location where they can be read easily.
- Preferable conduct the test in a secluded area.
- Before beginning the hydro test, double-check that all pipeline and vessel supports are sturdy, in excellent condition, and have been examined.
- Depressurize by gently opening the exhaust valve.
- To release water open the lowest drain point.
- Wear protective gear at all times.
To conclude, hydrostatic testing carries risk, it is important to ensure safety to keep hazards at bay.
