# Industrial Specification: Headers/Manifolds

## 1. Technical Definition
Distribution and collection components in heat exchanger systems that manage fluid flow between multiple tubes or channels.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25 bar differential pressure, -40°C to 200°C fluid temperature**. Failure boundary: **35 bar differential pressure causing material yield stress exceedance at 250 MPa, 250°C causing thermal expansion mismatch exceeding 0.5 mm differential displacement**, Mechanism: **High-cycle fatigue from turbulent flow-induced vibration at Reynolds numbers &gt;4000, galvanic corrosion at dissimilar metal interfaces with &gt;0.25V electrochemical potential difference**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

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

### Q: What materials are best for headers/manifolds in corrosive environments?
**A**: Stainless steel or copper alloys are recommended for corrosive environments due to their excellent corrosion resistance and durability in harsh industrial applications.

### Q: How do internal baffles improve heat exchanger header performance?
**A**: Internal baffles optimize fluid flow distribution, prevent channeling, enhance heat transfer efficiency, and reduce pressure drops across the header system.

### Q: What specifications should I consider when ordering custom headers/manifolds?
**A**: Key specifications include material type, pressure rating, temperature range, connection sizes (tube and flange), baffle configuration, and any required drain/vent port locations.

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
