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.

⸻
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.
