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

### Q: What materials are commonly used for heating jackets and coils in machinery manufacturing?
**A**: Common materials include Stainless Steel 316L for corrosion resistance, Incoloy 800 for high-temperature applications, and Carbon Steel for cost-effective solutions in non-corrosive environments.

### Q: What are the key components in a heating jacket or coil system?
**A**: The main components are connection nozzles for fluid inlet/outlet, heating coils for heat transfer, an insulation layer to minimize heat loss, and the jacket shell that encloses the system.

### Q: How do heating jackets and coils maintain tank temperature in industrial applications?
**A**: They circulate heating media (like steam or thermal oil) through coils within the jacket, transferring heat to the tank contents to maintain or raise temperatures for processes like chemical reactions or material storage.
