# Industrial Specification: Header Pipe

## 1. Technical Definition
A pipe that collects and distributes steam from multiple sources to various outlets within a steam header system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25.0 bar at 120-250°C**. Failure boundary: **Yield strength exceeded at 38.7 bar internal pressure (ASTM A106 Grade B, 241 MPa yield)**, Mechanism: **Thermal fatigue from cyclic stress exceeding 0.2% proof stress due to ΔT&gt;150°C temperature differentials between steam sources**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Water hammer pressure surge exceeding 2.5x design pressure | 8 | Pipe wall rupture at longitudinal weld seam | Installation of 0.5s response time pressure relief valves with 1.3x MAWP setpoint |
| Corrosion rate &gt;0.5 mm/year from dissolved oxygen &gt;15 ppb | 8 | Wall thinning to &lt;2.0 mm remaining thickness | Continuous deaeration maintaining &lt;7 ppb dissolved oxygen with automated chemical dosing |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

| spec | Config-dependent | mm | Verified |

## 4. System BOM & Knowledge Routing
### Core Components (Recursive Links)

### Industrial DNA Context (De-duplicated)
**Complementary Dependencies**: **Steam Boiler**, **Steam Trap**, **Pressure Reducing Valve**  
**Downstream Applications**: Steam Distribution System, Process Heating Equipment, Steam Turbine System  

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

### Q: What materials are best for header pipes in steam systems?
**A**: Carbon steel offers cost-effective durability for standard steam applications, while stainless steel provides superior corrosion resistance for high-purity or corrosive steam environments in machinery manufacturing.

### Q: What components are included in a typical header pipe BOM?
**A**: A standard bill of materials includes the main pipe section for steam collection/distribution, flange connections for secure system integration, and support brackets for proper installation and structural stability.

### Q: How do header pipes improve steam system efficiency?
**A**: Header pipes consolidate steam from multiple sources into a single distribution point, reducing pressure drops, minimizing heat loss, and ensuring consistent steam delivery to various outlets within industrial machinery systems.

## 6. Manufacturing Compliance
- ISO 9001:2015 QUALITY MANAGEMENT SYSTEMS
- EN 10255:2004 NON-ALLOY STEEL TUBES SUITABLE FOR WELDING AND THREADING - TECHNICAL DELIVERY CONDITIONS
