The immediate impression is that it looks somewhat fragile for 63 Bars, and if We make reverse engineering on the...
Let me update my question......or rephrase
Plate Heat Exchanger with design pressure 16 Bar.
This unit will be tested in the following way at our facility.
Test Test Pressure Tracer Medium
Factory tests Hydrostatic Pressure/Mechanical Test 22.8 Bar Water
Factory tests Vacuum...
We manufacture pressure vessels and execute 3 integrity/release tests ahead of shipping the units.
1. Hydrostatic Testing 1,43 x design pressure (30 min)
2. Vaccum Test (Pull Down to full vacuum)
3. Helium Leak Testing (8 Bars Helium)
At commisioning the customer executes a leak test using...
