# Industrial Specification: Collector Header

## 1. Technical Definition
A distribution manifold in resin underdrain systems that collects and channels filtered water from multiple laterals.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 bar (7.25-43.5 psi)**. Failure boundary: **4.2 bar (60.9 psi) internal pressure causing permanent plastic deformation in HDPE material**, Mechanism: **Exceeding the yield strength of high-density polyethylene (HDPE) at 25 MPa, combined with stress concentration at lateral connection points due to notch sensitivity factor of 1.8**.

### 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 |
| :--- | :--- | :--- | :--- |
| Biofilm accumulation exceeding 2 mm thickness in lateral channels | 8 | Flow restriction causing 40% pressure drop across header | Install UV-C disinfection at 254 nm wavelength with 30 mJ/cm² dosage upstream |
| Thermal cycling between 5°C and 45°C at 3 cycles/day | 8 | Stress cracking at injection-molded seams due to coefficient of thermal expansion mismatch (150 μm/m·K HDPE vs 11 μm/m·K stainless steel fittings) | Implement expansion loops with 300 mm radius and glass-filled polypropylene transition fittings |

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

**Downstream Applications**: Purified Water, Process Water, Wastewater Effluent  

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

### Q: What materials are recommended for collector headers in corrosive chemical environments?
**A**: For corrosive chemical environments, we recommend 316L stainless steel for high corrosion resistance, CPVC for excellent chemical compatibility at moderate temperatures, or polypropylene for cost-effective corrosion resistance in various chemical processes.

### Q: How does the collector header integrate with resin underdrain systems?
**A**: The collector header serves as the central distribution manifold that connects to multiple lateral pipes in resin underdrain systems. It collects filtered water from all laterals and channels it through a single outlet connection, ensuring efficient water collection and system performance.

### Q: What are the key components in a collector header BOM for chemical manufacturing?
**A**: The essential BOM components include: main header pipe (primary collection channel), lateral connection ports (for attaching underdrain laterals), outlet flange/connection (for system integration), and support brackets (for structural stability in chemical processing installations).

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