Hydrostatic testing (also known as “hydro-testing” or “pressure testing”) is the process of checking piping systems, gas cylinders, builders, and pressure vessels for strength and leakage. Hydrostatic testing is often seen after shutdowns or repairs as equipment must be checked and validated before going into service operation again. Testing must be done when the equipment is shut down in order to monitor for any abnormal conditions or signs of leaking.
The hydrostatic test consists of filling a piece of equipment with a fluid at test pressure, for a given period of time, to check the existence of leakages – The test is passed if the equipment bears the test pressure without any leakage.
The hydrostatic test is a common procedure to test piping equipment, like pipes, valves, and fittings (i.e. all products that shall withstand pressure when in operation.
When this type of test is not possible or recommended, the pneumatic test is a suitable alternative.
The hydro test is executed by skilled personnel by using chlorinated water (or other colored fluids) to check the existence of leakages in pressure-containing equipment. Before starting a hydrostatic test, the staff should pay attention to the testing fluid chemistry and how it may impact the equipment. Furthermore, hydrostatic testing cannot be performed during normal operations and cannot monitor equipment for leaks after the test has been performed. Although hydrostatic testing is considered to be a nondestructive testing method, equipment can rupture and fail if the inspection exceeds a specified test pressure or if a small crack propagates rapidly.
EcoTest 400: Hydro Testing Fluid
The material is virtually non-toxic to human health, non-hazardous and is fully compatible with water-based hydro-testing fluids such as propylene glycol. The product has been freeze tested for stability and the fluid retains the ability to be easily pumped, even at -40º Celsius.
Equipment Rentals: Filter Units & Hydro Test Wagons
Novamen provides various filtration systems and hydrotest wagons for on-site filtration and small hydro testing jobs.
Hydro Testing Fluid Services: Fluid & Equipment Rental Packages
Novamen’s hydro testing fluid rental service is a great way for our customers to complete their winter hydro testing programs without the need to purchase and dispose of these fluids. We carry large volumes which are available for short, medium and long term rentals. This service includes transportation to and from the test site, and can include tank rentals if needed.
Methanol
With a freezing point of nearly -100º Celsius, methanol has become an industry standard for winter hydro-testing applications across Canada. Methanol is relatively inexpensive and is considered to be an effective option in dilutions as low as 30%. Novamen has methanol in a variety of mixtures including a large supply of 50% methanol-water mix.
Propylene Glycol: Industrial Grade
Propylene glycol is often used in applications where environmental sensitivity is required and ethylene glycol is not recommended. Propylene glycol is widely employed in numerous industries. It has a wide range of practical applications
Tank Rentals
We offer both single and double-walled storage tanks to our customers for on-site storage of our chemicals in 200 to 400 barrel capacity.
