How to check whether the spiral plate heat exchanger meets the standard after the equipment is completed?

In general, the spiral plate heat exchanger will be tested for air tightness by air pressure to test whether there are two channels.

Leaks, cracks, etc. When the pressure is less than 8MPA, air pressure is generally used. When the pressure is greater than 8MPA,

It is safer to choose hydrostatic test. Usually, the pressure test is a single channel pressure test to ensure that the single channel pressure is positive in the later period.

Often. For details, please consult Zhongfan Industry, Wuxi spiral plate heat exchanger manufacturer.
