Piping Material Selection
| Material | Max Temp | Best For |
|---|---|---|
| Polypropylene | 180F | General lab use |
| PVDF | 280F | High purity, high temp |
| CPVC | 200F | Cost-effective |
| Borosilicate Glass | 450F | Solvents, visibility |
| HDPE | 140F | Underground |
Code Requirements
- Acid waste must be separate from sanitary
- Neutralization required before discharge
- pH monitoring may be required
- Double containment for concentrated acids
- Fire-rated penetrations required
