If you are building or maintaining a system that has pipes, valves, or vessels under pressure, you want to make sure that these components will perform as intended. A system failure could lead to employee or consumer injuries, damaged equipment, and lost productivity. There are a few different kinds of pressure testing that may be performed on systems.
What is Proof Pressure Testing?
Many people want to know, what is Proof Pressure testing? In this kind of testing, the evaluator pumps a material (air, or another gas or a liquid) into the items under test at a pressure that is slightly more than the intended operating pressure. The tester checks to see if the system leaks or sustains permanent damage. This kind of testing is not intended to damage the item; it is non-destructive.
What is Burst Pressure Testing?
A burst pressure test is a destructive test that measures the point at which the component will fail. The tester pumps the gas or liquid into the item until it is damaged. You want the pressure at which the system fails to exceed the operating pressure as much as feasible. This provides a margin of safety to the device.
What is Leak Pressure Testing?
Leak pressure testing involves placing the item under test into water. The item is filled with air or liquid, and then checked for leaks into the water. This kind of testing is particularly important if leaks could lead to environmental hazards and wasted materials.
What is Transient Pressure Testing?
Transient pressure testing checks for how the system performs under rapid pressure changes. The test plan should include those pressure changes that might be expected in the course of daily operations.
With a solid understanding of proof, burst, leak, and transient pressure testing, you can better ensure that your system will perform as intended, keeping people and products safe from harm.
