# Industrial Specification: Headers / Manifolds

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

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25 bar (gauge pressure), -40°C to 200°C fluid temperature**. Failure boundary: **Yield strength exceeded at 275 MPa (for 316L stainless steel), burst pressure at 62.5 bar, thermal stress cracking at ΔT &gt; 150°C across manifold**, Mechanism: **High-cycle fatigue from pressure pulsations (&gt;10⁶ cycles at &gt;15% of yield stress), stress corrosion cracking in chloride environments (&gt;50 ppm Cl⁻ at &gt;60°C), erosion-corrosion at fluid velocities &gt;3 m/s**.

### 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.
