Hydrostatic testing

Industrial boilers often require a hydrostatic test.

There are often many questions asked about hydrostatic testing in terms of how it works and also its benefits to  you and your business.

As there seems to be little to no information out there for interested parties, Hose Testing has decided to compile a small selection of the more burning questions we receive.

What is hydrostatic?

It’s a bit difficult to describe this in terms that don’t come across as completely scientific but in essence, hydrostatic is usually used in conjunction with pressure. Hydrostatic pressure is the amount of exertion evident in an area’s surroundings by water volume. Think of being at the bottom of the ocean and how heavy the weight of the water enveloping you would be and then apply it to a practical sense.


Why use water?

There are many reasons for this, one of them being the obvious abundance of water wherever you are.  This offers an economic option to all businesses (NOTE: you must check the quality and purity of water before testing).

Additionally, water is uncompressible and is versatile when it comes to testing.


How can I tell the results of a hydrostatic test?

Rather than having machine upon machine, all deciphering data and readings at once, hydrostatic testing’s results are noticed by eye.

It’s worthwhile and sometimes compulsory to perform a hydrostatic test with any new water vessel. This ensures that your item is in perfect condition upon arrival and is always preferable against leakage on the first practical application.

Simply put, you will be able to see if your vessel has failed the hydrostatic test if there is water leakage after it has been pressurised with water. If your item deforms down to excess pressure, it may not be suitable for the workplace.


What can I try a hydrostatic test on?

Upon most vessels that carry liquid as well as gases. Plumbing works, pipelines, boilers and gas cylinders are just a few of the instances where it is suitable.


How often should I test?

The relatively frequent testing of your vessel is actually statutory in some instances. Prior to application, all items will require a test and annually from there on.

This is essentially just assurance that your product is still working to safe levels and if it isn’t, it’s better to be safe than sorry by buying a new one instead of chancing health and safety dangers with an old unit.


How can I perform a hydrostatic test?

It is not advised (particularly if it’s your first time) to undertake the process yourself. Be sure to consult leading companies in hydrostatic testing who will be able to assist you and your business based against your requirements.
