The DN20-200 Corrosion-Resistant Aluminum Pipe for Air Systems addresses the critical challenge of maintaining air quality in harsh industrial environments. Constructed from 3003 aluminum alloy—formulated with 1.2% manganese to enhance corrosion resistance—this piping system offers superior protection against moisture, chemicals, and environmental contaminants . Available in sizes from DN20 (3/4 inch) to DN200 (8 inches), it maintains an operating pressure of 165 psi (11.4 bar) across all sizes, with a temperature range of -40°F to 212°F (-40°C to 100°C). The pipe’s surface undergoes a proprietary anodizing process that creates a 0.0005-inch thick protective oxide layer, ensuring long-term performance in humid or chemically exposed environments where standard aluminum pipes would degrade.
The 3003 aluminum alloy’s manganese content creates a naturally corrosion-resistant material that outperforms pure aluminum by 400% in salt spray testing (ASTM B117), making it ideal for coastal facilities or humid environments .
The electrochemical anodizing process forms a hard, porous oxide layer that accepts sealants, further enhancing corrosion resistance. This treatment also improves surface hardness to 60 Rockwell B, reducing damage from handling and installation .
The smooth internal surface (Ra < 0.8 μm) prevents moisture retention and bacterial growth, meeting cleanliness standards for food processing and pharmaceutical manufacturing facilities .
Unlike plastic piping, this aluminum system can be welded using TIG or MIG processes, creating permanent joints that eliminate potential leak points in critical applications.
This corrosion-resistant piping excels in:
• Food and Beverage Processing: Sanitary air lines in washdown environments.
• Coastal Industrial Facilities: Air systems resistant to saltwater exposure.
• Wastewater Treatment Plants: Compressed air lines in moisture-rich environments.
• Pharmaceutical Manufacturing: Clean air distribution meeting cGMP standards.
• Chemical Processing Plants: Non-reactive piping for instrument air systems.
3003 aluminum offers 30% better general corrosion resistance than 6061, particularly in humid environments, though 6061 provides higher strength. This makes 3003 ideal for corrosion-prone applications .
Yes, the anodized surface is compatible with standard compressor oils. Regular filter maintenance is recommended to prevent oil buildup in the system.
With proper installation, the pipe achieves a service life of 15-20 years in coastal areas, compared to 5-7 years for unprotected steel piping.
Yes, it resists degradation from common industrial cleaners, including sodium hydroxide solutions up to 5% concentration at room temperature.
