Pressure Testing Solutions
Pressure testing is used to check parts for strength and leaks prior to use. It is extremely important to ensure the proper operation and safety of a pressure vessel. There are a variety of pressure test processes, each providing a different, specific check on the pressure vessel.
The Experts in Integrated Pressure Testing Equipment
When you need to integrate a pressure test unit into your assembly verification application, turn to Cincinnati Test Systems. You can rely on our 40+ years of experience in designing and building pressure testing equipment, and our expertise in a range of pressure test applications.Contact Us
Pressure Decay/Vacuum Decay Testing
This is the single most common pressure test unit used in leak testing today. The test fills or charges the part to a target pressure, isolates that pressure, and measures the decay of pressure over a fixed time. The result can be displayed in three ways: scc/m leak rate, ∆P (overall pressure variation) or ∆P/∆T (pressure variation/time). We offer a range of pressure decay/vacuum decay leak testing equipment options to give you the perfect solution for your unique needs.
Occlusion testing is used to detect blockage (occlusion) of a passage within a pressure vessel. This test uses constant applied pressure from a fixed source to detect open or partially closed (blocked) states by measuring and recording backpressure at the inlet (upstream) of the part at the end of a fixed time. Our occlusion test systems utilize mass flow technology to ensure reliable results and repeatability.
Pressure Rise Testing/Pressure Increase Testing
These pressure test systems are used for multiple purposes, including the detection of leakage from a part or to detect restrictions and/or blockage within the part under test. The test, in most cases, operates by measuring any rise in pressure on the lower pressure side of a barrier or wall designed to be sealed off from a higher pressure side (often a part tested within a chamber). CTS pressure rise leak testing equipment is engineered to detect even the smallest leaks in sealed parts.
Proof testing is a technique used to stress the part under test to ensure it can maintain a certain level of pressure or vacuum for a period of time without gross failure. The test operates by ramping pressure or vacuum to the test part at a fixed rate for a fixed period and then holding that final pressure for an additional fixed time. Any drop below a minimum pressure level indicates the part has failed. Our proof testing units use state-of-the-art technology to deliver reliable results via customizable test processes.
Ramp to ∆P Event Testing
This testing method is generally used to test check valves, pressure relief valves, or other products designed to drastically change state (vent or seal) when pressure is increased or decreased. It is also often used for burst testing. In this test, pressure to the test part is ramped up or down at a fixed rate until a sudden change of pressure is seen on the inlet of the part, indicating the change in state or “event”; any event (pressure change) detected above or below the pressure set point range is identified as a failure with the measurement identified. Our ramp to ∆P event pressure testing units feature advanced test algorithms for superior accuracy and reliability.
Hydraulic Testing & Hydrostatic Testing
Hydrostatic testing is used to test a vessel or cavity for leaks, as well as structural strength and pressure tightness. CTS can design, build, and integrate low and high pressure hydrostatic testing instruments for burst, leak, flow, calibration, or integrity testing of your parts. Our hydrostatic pressure testing units can include manual or automatic testing capabilities, automatic part load/unload features, and are designed to collect detailed data for test evaluation.
