We have several modular stands that permit us to carry out various pressure tests using different media under different temperature conditions. Among others, testing resistance to bursting pressure or high-pressure pulsation tests are carried out.
On this page:
High-pressure pulsations or pressure change resistance tests are usually performed in the pressure range from 0 to 200 bar; to meet special requirements it is also possible to carry out such tests at higher pressures. Testing can be performed using different types of media at a wide range of temperatures.
We often carry out tests according to DIN SPEC 74104.

Burst tests, commonly called burst pressure resistance tests, are typically carried out at pressures up to 1000 bar with different media at varying ambient temperatures.

We can conduct tightness tests with any holding time and at a constant pressure value, or with a variable pressure trace.
Temperature range
Available working fluids
Tests of objects’ tightness following ageing tests (or taking samples from the production process) concern subjecting the object to the required pressure (or underpressure), under specified environmental conditions. The object’s medium can be gas (for example air, helium, nitrogen, cooling fluids, etc.) or liquid (water, ethyl glycol, etc.). Entire components, such as, for example heat exchangers, tanks, hoses, specific closed systems, etc. can be subjected to tightness tests.

Tightness tests of objects can be carried out using various techniques. The choice of technique depends on the expected accuracy of the measurement or the magnitude of the leak – the most accurate leak testing technique is the use of a vacuum method with a mass detector. The test is carried out on an object filled with helium, at atmospheric or elevated pressure (up to 250 bar or more), placed in a vacuum chamber connected to a mass detector. The test can detect leaks of the order of 10-12 mbar•l/s. Using an additional sensor (a sniffer), it is possible to locate points/areas of leakage on the order of 10-7 mbar•l/s.
