Marine-Grade PVC Ducts: A Corrosion-Resistant Solution for Ship Ventilation Systems

Challenges in Traditional Ship Ventilation Systems

Metal ventilation ducts in marine environments commonly face:

• Corrosion from saltwater exposure
• Condensation buildup
• Frequent maintenance requirements

PVC Flexible Ducts: Key Features

1. Material Composition

Marine-grade PVC material offers:

• Resistance to saltwater corrosion
• Lightweight construction
• Flexibility for easier installation

2. Structural Reinforcement

Spiral steel wire reinforcement provides:

• Structural stability under negative pressure
• Maintains duct shape during operation
• Typically spaced at regular intervals (exact spacing varies by specification)

3. Compliance Considerations

Quality marine PVC ducts should meet:

• Relevant marine equipment directives
• Classification society requirements
• Fire safety standards for marine applications

Implementation Considerations

When selecting marine ventilation ducts:

1. Verify material certifications with manufacturer
2. Confirm pressure rating meets system requirements
3. Ensure proper fire safety ratings for intended space
