Hydro Pressure Testing Machine | Tensile Testing Machine | MFI Testing Machine

Hydro Pressure Testing Machine is a nondestructive testing (NDT) method of finding leaks or verifying performance and durability in pressure vessels such as pipe, tubing, and coils. Although this is considered nondestructive testing and failures are rare, they can occur when the test piece does not meet performance or durability specifications and may render the piece unusable.

This type of testing usually entails filling the test piece with liquid, bleeding out air, pressurizing the piece, and then examining it for leaks or permanent changes in shape. A nearly incompressible (compressible only by weight, not air pressure) liquid, usually water or oil, is used because it will only expand by a very small amount should the test piece fail. The other reason for using these liquids is they do not pose a danger to the testing technician. Hydro Pressure Testing Machine can be performed with pressurized air, but the test is generally done while the vessel is under water for safety reasons.

The amount of pressure used in hydrostatic pressure testing is always considerably more than the operating pressure, or the pressure the vessel will be subjected to in the course of operation, to give the customer a margin for safety. Typically the test is performed at 150 percent of the design or working pressure. For example, if a pipe was rated to a working pressure of 2000 PSI, it would be tested at 3000 PSI.

Inspections at Laboratory Testing

At Laboratory Testing, we are equipped to do Hydro Pressure Testing Machine with water, oil, or air under water. Water is the most commonly used test medium because it is less expensive than oil and an easier set up than air, so the cost of testing is lower. Nondestructive testing NDT technicians test tubing, pipe and coils to pressures up to 10,000 PSI, in many cases. All hydrostatic pressure testing is performed according to customer requirements and/or industry specifications.
