The inspection process before a heat exchanger is ready to go

The inspection of the plate heat exchanger mainly includes the review of raw materials, pressure tests after processes. The main contents are as follows: 

1. Raw materials and spare parts size and geometry inspection of the plate heat exchanger.  

2. Inspection of internal defects of raw materials and welds. The inspection method is non-destructive testing, which includes: X-ray detection, ultrasonic detection, magnetic particle detection, penetration detection, etc. 

3. Weld quality testing

The weld quality testing includes chemical composition analysis, mechanical properties analysis test, metallographic structure test, etc.

4. Pressure test

The pressure test of the heat exchange includes water pressure test, medium test, airtight test, etc. 

5. Airtightness test

After all needed tests are qualified before leaving the factory, they can be regarded as qualified products.
