## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in View Port construction for VPI chambers?
**A**: View Ports are constructed with tempered glass or polycarbonate transparent panes, mounted in stainless steel flanges with sealing gaskets and clamping rings for secure, leak-proof installation.

### Q: Why is visual inspection important in Vacuum-Pressure Impregnation processes?
**A**: Visual inspection through View Ports allows operators to monitor impregnation quality, detect air bubbles or incomplete saturation, and ensure proper material flow without opening the chamber and breaking vacuum/pressure conditions.

### Q: How do View Ports maintain seal integrity in VPI chambers?
**A**: View Ports use specialized sealing gaskets and precision-machined stainless steel flanges that maintain vacuum and pressure integrity while withstanding thermal cycling and chemical exposure during impregnation processes.
