# Industrial Specification: Cooling Headers (Water/Air)

## 1. Technical Definition
Cooling headers are components that distribute cooling medium (water or air) to specific zones of a runout table to control temperature during material processing.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.0-6.0 bar (water), 0.5-2.0 bar (air)**. Failure boundary: **Water: 8.0 bar (burst pressure), Air: 3.5 bar (structural deformation), Temperature: 150°C (polymer seal degradation)**, Mechanism: **Water headers: Cavitation at vapor pressure &lt;0.023 bar at 20°C causing pitting; Air headers: Laminar-turbulent transition at Reynolds number &gt;2300 causing vibration-induced fatigue**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| U | Heat Transfer Coeff | Engineering Constant |
| A | Area | Engineering Constant |
| \Delta T_{lm} | LMTD | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Calcium carbonate scaling at saturation index &gt;0.5 | 8 | Flow reduction to &lt;60% design capacity | Phosphonate-based scale inhibitor injection at 2-5 ppm concentration |
| Thermal cycling ΔT &gt;80°C/min | 8 | 304 stainless steel header cracking at stress &gt;205 MPa | Inconel 625 thermal expansion joints with 15% elongation capacity |

- **Caution**: 
- **Caution**: 

### Q: What materials are available for cooling headers in metal manufacturing?
**A**: Our cooling headers are manufactured from durable materials including stainless steel for corrosion resistance, carbon steel for strength, and aluminum alloy for lightweight applications in basic metal processing.

### Q: How do cooling headers improve temperature control on runout tables?
**A**: Cooling headers distribute water or air precisely to specific zones of the runout table, enabling controlled cooling during material processing to achieve consistent metallurgical properties and dimensional stability.

### Q: What components are included in a typical cooling header BOM?
**A**: A complete cooling header system includes header pipes for distribution, control valves for flow regulation, nozzle assemblies for targeted application, and mounting brackets for secure installation in industrial environments.
