Pressure Cycle Test Stand | Impulse Test

In order to prove the quality of the fluid-carrying parts, all hoses, pipes, pressure vessels and other components are put under pressure until they burst. The process is precisely measured and documented in order to optimally design the components for specific applications.

The system is a self-sufficient unit and is made of a solid welded frame, contains media preparation, a hydraulic unit, and electrical engineering. The pressure test bench has a secure test chamber for burst pressure and hydrostatic pressure tests and, optionally, a climatic chamber for pressure tests with environmental simulation. Depending on the option selected, pressure change tests up to 2,000 bar and 10 Hz can be generated. With the test circuit for hydrostatic and burst pressure tests, pressure ramps up to 3,000 bar can be generated. It is operated on a support arm PC. For pressure tests according to EG79 / EU406 – Section 4.2 Pressure booster for additional supply Displacement volume max. 15cm³ Frequency up to 10Hz Pressure Load Changes as sine & trapezoidal curve (depending on the expansion volume) Impulse intensifier for small volumes up to 2,000bar Safety test chamber with automatic door Media treatment with dirt and clean tank

With the dual chamber PPM leak test stand, Poppe + Potthoff Maschinenbau offers a powerful system for testing sensors in medical device industry. The test stand can be implemented in R&D processes, but also during production as an end of line test. With pressures of up to 50 bars this equipment offers a large spectrum of testing opportunities in the medical area. Some Global Test Standards include: ISO 14644 ASTM G122-96 ASTM D6361 SAE AMS 0302 The PPM leak test stand is able to be programed to the customers requirement. The powerful in house built software enables exact design of pressure curves, such as holding times and exact pressure increase over time. It is an ideal solution for any sorts of plastic components. This exemplarily displayed test bench can utilize air or nitrogen as a test medium. Please get in touch about any other test mediums. In addition the PPM test benches can perform tests of multiple test units at a time.

Autofrettage is a method for increasing fatigue strength of components for use at high and pulsating pressures. In short, Autofrettage compresses a container’s inner surface, making better use of the material’s structural properties. The process can reduce fatigue concerns in pulsating applications and lets engineers reduce tubing thickness in high-pressure applications without sacrificing strength, life, or safety. The autofrettage method is based on the reciprocal relationship of the plasticized inner zone and the elastically deformed outer zone. The components are placed under so much pressure that their interiors become plastically deformed. After relaxing, pressure stresses are created in these areas, which prevent the outer areas from reforming to their original shape. Instead, it remains stretched. This prevents crack formation in the later application, increases the service life of
