# Industrial Specification: Manifold/Distribution Header

## 1. Technical Definition
A component in cooling systems that distributes coolant from a single source to multiple outlets or collects it from multiple inlets to a single outlet.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25 bar (gauge pressure), -20°C to 120°C coolant temperature**. Failure boundary: **35 bar burst pressure for carbon steel, 28 bar for 316L stainless steel, 150°C thermal deformation threshold**, Mechanism: **Yield strength exceedance at 250 MPa for carbon steel (ASTM A106) or 205 MPa for 316L stainless steel (ASTM A240) causing plastic deformation; differential thermal expansion coefficient mismatch (11.7 μm/m·K for carbon steel vs 16.0 μm/m·K for copper fittings) inducing stress concentrations**.

### 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.

- **Caution**: 

### Q: What materials are best for corrosion resistance in manifold/distribution headers?
**A**: Stainless steel offers excellent corrosion resistance for harsh environments, while brass provides good corrosion resistance at lower cost. Aluminum alloy is lightweight but may require coatings for certain coolants.

### Q: How do I select the right port fittings for my cooling system manifold?
**A**: Consider coolant type, pressure rating, temperature range, and connection standards (NPT, BSP, SAE). Match port size to your system's flow requirements and ensure compatibility with seals/gaskets for leak-free operation.

### Q: What maintenance is required for distribution headers in industrial cooling systems?
**A**: Regular inspection of seals/gaskets for wear, checking for corrosion or mineral buildup in ports, and verifying mounting bracket integrity. Follow manufacturer specifications for torque values on fittings to prevent leaks.

## 6. Manufacturing Compliance
- ISO 9001:2015 (QUALITY MANAGEMENT SYSTEMS)
- PED 2014/68/EU (PRESSURE EQUIPMENT DIRECTIVE)
