# Industrial Specification: Spray Headers

## 1. Technical Definition
Distribution manifold that supplies cooling fluid to multiple spray nozzles in a cooling spray system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.5-15.0 bar**. Failure boundary: **18.7 bar internal pressure (yield strength threshold)**, Mechanism: **Plastic deformation due to hoop stress exceeding material yield strength (σ_θ = P·r/t &gt; σ_y)**.

### 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 available for spray headers in machinery cooling systems?
**A**: Our spray headers are manufactured in Stainless Steel 304/316 for corrosion resistance, Carbon Steel for strength and cost-effectiveness, and Brass for compatibility with various fluids and moderate corrosion resistance.

### Q: How do spray headers distribute fluid in cooling spray systems?
**A**: Spray headers function as distribution manifolds that receive cooling fluid through a single inlet connection and evenly distribute it through multiple outlet ports to supply spray nozzles, ensuring consistent cooling across machinery components.

### Q: What components are included in a typical spray header BOM?
**A**: A standard spray header bill of materials includes the header body (main manifold), inlet connection for fluid supply, multiple outlet ports for nozzle attachment, and mounting brackets for secure installation in machinery cooling systems.

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