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

### Q: What are the main material options for industrial cooling jackets?
**A**: Our cooling jackets are available in carbon steel for general applications and stainless steel (304/316 grades) for corrosive environments or sanitary requirements.

### Q: How do the internal baffles or channels improve cooling performance?
**A**: Internal baffles create controlled fluid flow paths that maximize heat transfer efficiency and ensure uniform temperature distribution around the barrel section.

### Q: What sealing components are included with cooling jackets?
**A**: Each jacket comes with high-quality sealing gaskets or O-rings to prevent coolant leakage and maintain system integrity under operational pressures.

## 6. Manufacturing Compliance
