Keep Your Air System Flowing Smoothly
Compressed air is only as reliable as the piping that delivers it. Legacy Industries provides expert maintenance and repair for air piping systems made of aluminum, black iron, copper, and stainless steel. Our technicians locate and fix leaks, remove obstructions, and restore balanced pressure throughout your network — keeping your plant efficient, safe, and compliant.
⸻
Common Air Piping Problems We Fix
| Problem | Typical Cause | Our Solution |
|---|---|---|
| Air leaks at joints or fittings | Vibration, age, improper sealing | Ultrasonic leak detection and precision resealing |
| Pressure drop between tools | Undersized lines or flow restrictions | Pipe resizing, rerouting, and flow balancing |
| Moisture in airlines | Improper slope or failed drains | Drain maintenance, trap replacement, re-slope piping |
| Rust or corrosion | Condensation and contaminated air | Replace corroded sections with aluminum or coated steel |
| Clogged filters or valves | Neglected maintenance | Cleaning, filter replacement, and recalibration |
| Loud hissing or vibration | Unstable pressure or loose mounts | Secure supports, tune regulators, and balance the system |

Inspection and Leak Detection Process
1. System Evaluation
We begin with a walk-through of the facility, mapping your air piping routes, identifying pressure points, and listening for leaks.
2. Ultrasonic Leak Testing
Our tools detect even the smallest leaks, allowing us to pinpoint and tag each location without disrupting operations.
3. Verification and Pressure Testing
After sealing or replacing fittings, we re-pressurize the system to confirm a complete seal.
4. Documentation and Reporting
You receive a detailed report outlining every repair, pressure reading, and energy savings estimate achieved through leak reduction.
⸻
Preventive Maintenance Scheduling
| Frequency | Tasks Included | Benefits |
|---|---|---|
| Monthly | Drain cleaning, pressure checks, leak scan | Keeps system dry and balanced |
| Quarterly | Filter replacement, ultrasonic leak testing | Prevents energy loss and contamination |
| Semiannual | Piping inspection and alignment check | Detects corrosion or sag before damage occurs |
| Annual | Full pressure audit and flow measurement | Tracks efficiency and supports budgeting for upgrades |
Each maintenance plan is customized for your environment, operating hours, and system design.

Energy Efficiency Through Leak Management
- Every 1/8-inch hole in a 100 psi line can waste over 1,000 dollars per year in electricity.
- Regular inspections reduce wasted air, lower compressor workload, and extend equipment life.
- Leak reduction also improves air tool performance and product consistency.
- Our technicians measure before and after performance to quantify savings for your records.
⸻
Repair and Replacement Options
Targeted Repairs
We repair small leaks and fittings on-site using approved sealants, gaskets, and compression joints without replacing full runs.
Partial Replacement
When a section of piping is corroded or undersized, we replace it with modern aluminum or coated steel while minimizing downtime.
Full System Upgrade
For aging facilities or repeated failures, we can redesign the network for improved flow, proper drainage, and pressure balance.

⸻
How to Know It’s Time for Service
- Audible hissing or unexplained pressure loss
- Higher compressor runtime and energy bills
- Reduced air pressure at production tools
- Moisture or rust in air outlets
- Vibrations or sudden pressure spikes
If you notice these signs, schedule a maintenance inspection before minor issues turn into major repairs.

Frequently Asked Questions
Can repairs be done without shutting down production?
Yes. Many leak repairs and fitting replacements can be performed under pressure using specialized tools and safe isolation practices.
How do you detect hidden leaks?
We use ultrasonic sensors that can identify leaks too small to hear, even in noisy environments.
Can aluminum and black iron be mixed in the same system?
Yes, but dielectric fittings are used to prevent galvanic corrosion and maintain safety.
Do you offer maintenance contracts?
Yes. We provide monthly, quarterly, or annual maintenance programs tailored to your operating schedule.
Do you provide documentation for audits?
Every service visit includes a written report with readings, leak locations, and parts replaced for your maintenance records.
