# Industrial Specification: Collection Manifold

## 1. Technical Definition
A distribution component that consolidates and directs fluid outputs from multiple microreactors into a single stream or designated outlets.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-15 MPa (1-150 bar)**. Failure boundary: **18.5 MPa (185 bar) internal pressure at 150°C**, Mechanism: **Yield strength degradation of 316L stainless steel (241 MPa at 20°C to 172 MPa at 150°C) leading to plastic deformation and creep rupture**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

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

### Q: What materials are recommended for corrosive chemical applications in collection manifolds?
**A**: For corrosive environments, PTFE (Polytetrafluoroethylene) or Glass manifolds offer superior chemical resistance. Stainless Steel 316L is suitable for most standard chemical processes but may not withstand highly aggressive acids or chlorides.

### Q: How does a collection manifold improve microreactor system efficiency?
**A**: A collection manifold consolidates outputs from multiple microreactors into a single stream or designated outlets, reducing connection points, minimizing potential leak points, simplifying downstream processing, and enabling more controlled fluid management in continuous flow systems.

### Q: What maintenance considerations are important for collection manifold seals?
**A**: Regular inspection of sealing gaskets and O-rings is crucial. PTFE gaskets offer excellent chemical resistance but may require periodic tightening. Ensure compatibility between seal materials and process fluids, and follow manufacturer torque specifications during assembly to prevent leaks.

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