All you need to know about a Hydro Pressure Test

A hydro pressure test as the name suggests is a way to test pressure vessels such as pipelines, plumbing, gas, cylinders, boilers and fuel tanks can be tested for strengths and leaks. The process involves filling a container or the pipe system with a liquid, usually water, which may be dyed to make the detection of leaks easier to spot. Pressurization of the container can be controlled to the specified test pressure. Pressure tightness can be tested by closing off the supply valve and checking whether there is a loss of pressure.

Is hydro pressure testing important?

Yes. In fact, it is of much importance that some countries have several regulations on this particular test. Tests range from the smaller simpler tests which deal with checking fire extinguishers and checking that it is free from leaks up to dealing the huge pressurized boilers in factories. What are the implications of such tests?

• Safety – regular periodic hydro testing ensures that the end user products are safe to use and free from leaks.

• Quality Control – it reduces the risk of defective pressurized vessels getting out into the market.

• Conservation of resources – since these tests can also be conducted on plumbing, it saves the end user from having unnecessary costs and prevents leaks which could potentially cause damage to property.

• Makes visual testing easier – after conducting a hydro pressure test, damaged and distorted vessels are easier to spot and replace.

• Helps aid customer requirements and specifications- a hydro pressure test can ensure that customer equipment requirements will be met.

Is a hydro pressure test dangerous?

Conducting such tests are potentially dangerous so it necessary that these tests shall be done by skilled and trained testers. Strict safety compliance should be followed and maintained while these tests are being conducted. This is to minimize the risk of accidents. It has been pointed out that a high-pressure liquid can cut in to the skin and can get into tissues so it is imperative to take obvious care in undertaking such procedures.

How do we minimize potential risk?

Go to a reputable company who offers such services. Do your research before getting into contract. Do not sacrifice safety in favor of price point. Make sure that the company you contract is fully equipped and have the necessary certifications to do testing.
