Plate Heat Exchanger Manufacturing Process

Plate heat exchanger manufacturing process inspection

 The inspection of the plate heat exchanger equipment manufacturing process, including the inspection of raw materials, the inspection between processes and the pressure test, the specific contents are as follows:

  1. Equipment pressure test, including: hydraulic test, medium test, airtight test etc.

  2. Inspection of the dimensions and geometry of raw materials and equipment parts

  3. Inspection of raw materials and weld internal defects, the inspection method is non-destructive testing, which includes radiation detection, ultrasonic inspection, magnetic particle detection and penetration inspection.

  4. Chemical composition analysis, mechanical property analysis test, metallographic structure inspection of raw materials and welds, collectively referred to as failure test.
