Compressed Air Piping Systems
Efficient Air Delivery for Every Industrial Application
Reliable compressed air systems start long before the air reaches your tools or machinery. The piping network, how air travels from the compressor to its point of use, determines system efficiency, safety, and overall performance. At Northwest Pump, we design and supply complete compressed air piping systems built for durability, purity, and long-term reliability.
Since 1959, our team has helped facilities across industries, from manufacturing and food processing to marine, wastewater, and aerospace, design systems that minimize pressure loss, reduce leaks, and optimize energy use.
The Importance of Piping Design
Even the most advanced compressor can’t perform without a well-planned piping network. Air piping influences system pressure, energy consumption, and air quality. A poorly designed system leads to higher operating costs, frequent downtime, and inconsistent air delivery.
Our experts help clients evaluate pipe materials, sizing, layout, and fitting design to ensure each system meets performance demands and complies with OSHA safety standards. From small workshops to multi-line production plants, the goal is always the same—efficient, clean, and reliable compressed air.
The Infinity Aluminum Piping Advantage
For facilities seeking a modern, high-performance alternative to steel, Infinity Piping systems offer the best of both worlds; lightweight construction with industrial-grade strength. Infinity aluminum piping is up to ten times lighter than steel, allowing faster installation, flexible design, and easier expansion as systems evolve.
Its non-corrosive interior ensures consistent air quality, and the system can also handle nitrogen, vacuum, and inert gases with equal efficiency. Infinity’s modular design eliminates the need for welding or special tools, reducing downtime and installation costs.
Northwest Pump proudly supplies Infinity Piping Systems as part of our complete line of compressed air solutions, backed by expert technical support and decades of field experience.
Choosing the Right Air Piping Material
Different facilities require different materials, and each comes with unique advantages and limitations.
Galvanized Steel
Long valued for its strength and affordability, galvanized steel is a common choice for air piping. However, it can corrode internally when moisture accumulates, leading to rust contamination and costly maintenance. Professional installation is essential, as welding and threading require skilled labor.
Stainless Steel
For facilities requiring sterile or contamination-free air—such as hospitals, laboratories, or pharmaceutical plants—stainless steel offers unmatched corrosion resistance and pressure tolerance. Though installation costs are higher, its longevity and purity make it ideal for critical applications.
Aluminum
Lightweight, corrosion-resistant, and easy to assemble, aluminum piping is now the preferred choice in many modern facilities. It provides smooth interior surfaces that maintain optimal flow and prevent buildup. Installers can modify layouts quickly, reducing labor time and installation cost.
Copper
While copper is exceptionally clean and corrosion-resistant, its high material cost and labor-intensive installation make it better suited for specialized applications where air purity is paramount, such as medical or dental environments.
Plastic
Plastic piping may appear cost-effective, but not all varieties are safe for compressed air. PVC, for example, can shatter under high pressure, posing a serious hazard. OSHA prohibits its use in most above-ground compressed air systems.
Best Practices for Compressed Air Piping System Design
- Plan for future expansion. Design piping layouts that allow easy system growth without major modifications.
- Minimize pressure drops. Use properly sized pipes and gentle directional changes to maintain consistent airflow.
- Eliminate leaks. Routine inspections and quality fittings prevent wasted energy and lost productivity.
- Control moisture. Incorporate air dryers, drains, and sloped piping to remove condensation before it reaches tools or equipment.
- Prioritize safety. Always use OSHA-approved materials and ensure piping systems meet manufacturer specifications for temperature and pressure.
Our engineers and field specialists can assist in evaluating your current setup or planning a new one from the ground up.
FAQs About Compressed Air Piping Systems
What is the best material for compressed air piping?
Aluminum offers the best balance of durability, safety, and cost efficiency for most industrial applications. Stainless steel is preferred in environments requiring sterile or high-purity air.
Can PVC piping be used for compressed air?
No. OSHA prohibits PVC for compressed air due to its risk of shattering under pressure. Safer alternatives include aluminum or stainless steel systems.
How does pipe size affect system efficiency?
Undersized piping restricts flow and causes pressure drops. Properly sized piping ensures even distribution and reduces compressor workload, saving energy.
What maintenance is required for air piping systems?
Regular inspections for leaks, corrosion, and moisture buildup are essential. Infinity aluminum systems require minimal upkeep thanks to their non-corrosive construction.
Can existing steel systems be upgraded to aluminum?
Yes. Many facilities retrofit legacy steel systems with aluminum for reduced weight, easier installation, and improved airflow efficiency.
Many facilities that rely on compressed air also run steam lines for cleaning, sanitation, or process heat. Northwest Pump supplies steam hose and fittings rated for those higher-pressure, higher-temperature applications as well.
