# Industrial Specification: Bath Tank

## 1. Technical Definition
The primary container within a deliming bath system that holds the chemical solution for processing hides.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-95°C, 0-2.5 bar**. Failure boundary: **Material yield strength at 120°C: 205 MPa for 316L stainless steel**, Mechanism: **Stress corrosion cracking due to chloride ion concentration exceeding 25 ppm at temperatures above 60°C, combined with tensile stresses from thermal cycling**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Chloride concentration buildup exceeding 50 ppm from hide processing residues | 8 | Intergranular corrosion initiating at weld heat-affected zones | Implement cathodic protection system with -850 mV vs. Ag/AgCl reference electrode potential |
| Thermal cycling between 20-90°C at frequency &gt;5 cycles/hour | 8 | Low-cycle fatigue crack propagation from stress concentration at nozzle junctions | Install expansion bellows with 15 mm axial movement capacity at all pipe connections |

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

### Q: What materials are best for a bath tank in leather deliming applications?
**A**: Stainless Steel 316L offers superior corrosion resistance against deliming chemicals, while Fiberglass Reinforced Plastic provides durability and chemical resistance at lower cost. Polypropylene is also suitable for certain chemical solutions.

### Q: How does the agitation system improve leather processing in a bath tank?
**A**: The agitation system ensures uniform chemical distribution throughout the deliming solution, preventing settling and ensuring consistent hide processing. This results in more uniform leather quality and reduces processing time.

### Q: What maintenance is required for a deliming bath tank?
**A**: Regular inspection of the heating/cooling jacket for leaks, cleaning of the level sensor to prevent false readings, and checking the drain valve for proper sealing. Material-specific cleaning protocols should be followed based on tank construction.
