The inspection in the manufacturing process of plate heat exchanger, including raw material inspection, inter process inspection and pressure test, is very strict. The following plate heat exchanger manufacturer will take you to know the plate heat exchanger quality inspection. 

1. Inspection of dimension and geometry of plate heat exchanger and equipment parts;

2. The chemical composition analysis, mechanical property analysis test and metallographic structure inspection of plate heat exchanger and weld are the important links of plate heat exchanger quality inspection.

3. The inspection method of plate heat exchanger and weld internal defects is non-destructive testing, which includes: radiographic testing, ultrasonic testing, magnetic particle testing, penetrant testing, etc;

4. Pressure test of plate heat exchanger equipment, including: hydrostatic test, medium test, air tightness test, etc.

At this point, I believe you have a general understanding of theplate heat exchanger quality inspection. Warmly welcome friends from all walks of life to negotiate business, we will be the best price, best quality, best service to meet your needs!
