Product Overview


The DN20-200 Aluminum Piping for Industrial Air delivers robust performance for medium to large-scale compressed air systems, covering a comprehensive size range from DN20 (3/4 inch) to DN200 (8 inches). Engineered from high-strength 6061-T6 aluminum alloy—tempered to achieve a minimum tensile strength of 38,000 psi—this piping system balances durability with lightweight handling for industrial environments . With a maximum operating pressure of 190 psi (13 bar) for DN20-DN100 sizes and 145 psi (10 bar) for DN125-DN200, it provides reliable airflow for heavy-duty applications where consistent pressure is critical. The system’s modular design allows for easy scalability, making it suitable for expanding industrial facilities.


Product Features


Wide Size Range for Versatile Applications

Covering DN20 to DN200, this piping system eliminates the need for multiple diameter-specific components, simplifying inventory management and system design for facilities with varying airflow requirements .


High-Strength Aluminum Alloy

The 6061-T6 aluminum construction offers excellent strength-to-weight ratio, with yield strength of 35,000 psi and elongation of 10%, allowing it to withstand industrial vibration and pressure fluctuations without fatigue .


Pressure Retention Optimization

Engineered with precise wall thicknesses (3.2mm for DN20 up to 8.0mm for DN200), the piping maintains consistent pressure across long runs, reducing energy waste compared to undersized systems .


Compatibility with Industrial Fittings

Designed to work with standard grooved, flanged, and threaded connections, the system integrates seamlessly with existing industrial air equipment, including compressors, dryers, and distribution manifolds.


Applications


This industrial air piping is ideal for:


Heavy Manufacturing: Large-scale production lines requiring high-volume air supply.

Power Plants: Compressed air systems for turbine control and auxiliary equipment.

Mining Operations: Rugged air distribution for pneumatic tools and ventilation.

Automotive Plants: High-pressure lines for robotic welding and assembly systems.

Chemical Facilities: Non-sparking air piping for hazardous environment compliance.


FAQ


What is the flow capacity of the largest DN200 size?

At 145 psi, the DN200 pipe delivers a maximum airflow of 10,500 CFM (cubic feet per minute), sufficient for large industrial complexes with multiple air-powered tools and processes.


How does the weight compare to steel piping of the same size?

DN20-200 aluminum piping weighs approximately 40% less than Schedule 40 steel pipes, reducing structural support requirements and installation labor costs.


What is the recommended spacing for pipe supports?

For DN20-DN50: 8 feet (2.4m) between supports; DN65-DN100: 10 feet (3.0m); DN125-DN200: 12 feet (3.6m) to prevent sagging under operating conditions.


Can this piping be used for other gases besides compressed air?

Yes, it is suitable for dry inert gases like nitrogen and argon, but not for corrosive gases or liquids without additional lining.
