Test benches for hydraulic tests of heat exchangers
Stands for hydraulic testing of tube, plate and spiral heat exchangers
Benches for hydraulic testing of tube, plate and spiral heat exchangers.
Test benches for hydraulic tests of heat exchangers are designed and manufactured individually in accordance with the customer's technical specifications.
As a rule the benches are connected to external armored chambers, armored tanks, test rooms of the customer.
Features of heat exchanger tests.
Besides standard pressure and leak tests, heat exchangers are also tested for hydraulic burst occurring in the internal chambers of the test piece.
It is not possible to visually register the moment of rupture in this case.
Visual detection of the moment of rupture is not possible in this case.
The burst pressure is detected by the pressure drop.
Pressure gauges with a maximum pressure pointer are used to record the burst pressure.
A gentle rise in discharge pressure is extremely important to capture the exact burst pressure.
For this purpose, a hydraulic pressure reducer is available downstream of any series pump at burst pressures below 700 bar or 5L-DD twin plunger pumps at pressures above 700 bar.
The pressure reducer is available downstream of any series pump at burst pressures below 700 bar.
