A hydrostatic test is a process for testing boilers, gas cylinders, pipelines, and in plumbing for testing the strength of pipes and identifying leaks. A hydrostatic test involves filling the lines with liquid, usually dyed water, to detect the leaks.
Using coloured water makes detection of the leak much easier and faster. A hydrostatic test also helps with checking and maintaining the integrity of utility lines and other pipelines.
How Does It Work?
A hydrostatic test works by filling the container or pipe with coloured water or liquid, removing the air from the pipe, and pressuring it 1.5 times the pressure limit of the pipe or container.
The pressure is maintained for a specific time until the leaks are found. The coloured liquid helps identify the leaks faster. For pipelines, the hydro test is conducted on pipelines that are currently out of service or turned off.
Make sure all pipes are clean and turned off before they are hydro tested.
What Are The Uses Of Hydrostatic Testing?
- To check the quality of equipment and pipes.
- To test for low pressure.
- To check for leaks.
- For safety checks of machines and pipes.
- To check for material or equipment flaws.
- To detect the presence of corrosion or cracking.
- To pinpoint the exact location of leaks for repairs.
The main purpose of hydrostatic testing is SAFETY. Whether it is for residential, commercial, or industrial use, hydro testing ensures your pipes and equipment are working properly and safely.
Hydro Testing For Residential Purposes
Under your home and inside your walls run complicated utility lines for plumbing, gas, electricity, and many other utilities. It is important to monitor the integrity of these lines to ensure your safety.
Gas line leaks can lead to a disaster while plumbing leaks can cause severe damage to not just your pipelines but also the foundations or your house or building.
Do not wait for leaking to occur. Arrange a regular schedule to check your pipes as part of your yearly maintenance. You will be surprised at the damage and accidents you can prevent by doing simple, regular maintenance checks.
Hydrostatic testing provides important information to your gas company about safety margins for the pipeline. It also allows preventative measures and repairs to avoid any toxic leaks, explosions, and other disasters.
What To Expect?
Hydrostatic testing requires planning. It takes some time to prepare for the test to ensure public safety and to minimise the inconvenience it may cause to the homeowners and the neighbourhood.
Your hydro-testing professionals need to conduct research and record-checking before they can start the actual test.
What Happens After the Hydro Test?
- No Leaks? – If the testing found no leaks and has determined your pipelines and equipment to be in good working condition, the test is deemed successful. The results need to be documented for future inspections. After the test, the next maintenance check should be scheduled.
- Leaks found – If the test found leaks and raptures in the pipeline, whether plumbing or gas lines, repairs need to be done immediately. Your inspectors will give the appropriate recommendations as soon as they get the results. Make sure you follow and adhere to their recommended course of action. You should make the repairs as soon as possible to avoid any fatal accidents.
Gas leaks are one of the most dangerous issues, especially if you have children in the house. If you suspect there is gas leaking in your area, do not try to fix it yourself. Leave it to the professionals. Call your local inspectors or fire department right away.
