Beijing plate heat exchanger the body expansion test of air separation equipment of switch plate heat exchanger in Beijing channel or pattern have specific requirements, should be on this test.
To Beijing is full of a plate heat exchanger unit cell channel plus pressure causes the channel volume expansion, increase into the channels of water, using deformation -
Time -
Pressure curve, can measure the brazing quality of the elements.
Beijing plate heat exchanger body expansion test and unit body hydrostatic test may be done at the same time.
This test and hydrostatic test at the same time, both the same test pressure.
