Achieve Maximize Efficiency and Productivity with CTS Test and Reclaim Systems

Pressure Testing Units

Pressure testing is used to parts for strength and leaks prior to use. There are a variety of pressure test processes, each of which provides a different, specific check on the pressure vessel. Pressure testing is extremely important to ensure the proper operation and safety of a 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 (CTS). With over thirty years of experience in designing and building pressure testing equipment, along with our expertise in pressure test applications that utilize methods like hydrostatic testing to proof testing, you can rest assured your test performance is optimized with the utmost safety in mind.

Hydraulic Test System

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.
 

Occlusion Testing

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 period. Our occlusion test systems utilize mass flow technology to ensure reliable results and repeatability.
 

Pressure Rise Testing/Pressure Increase Testing

These pressure test units 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 chamber around a filled or sealed tested part). CTS pressure rise leak testing equipment is engineered to detect even the smallest leaks in sealed parts.
 

Proof Testing

Proof testing is a technique used to stress the part under test to ensure it is capable of maintaining 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 period. 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. This type of pressure testing 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 detected above or below the expected range of final event inlet pressures is failed. Our ramp to ∆P event pressure testing units feature advanced test algorithms for superior accuracy and reliability.
 

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 period. The final result can be displayed in three ways: 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.
