Leak Detection

Gas Leak Survey

Ultrasonic gas leak detection for nitrogen and other process gas systems.

ISO 9001:2015 38+ Years Free Assessment
Gas Leak Survey — Permaweld industrial engineers at work

Detects leaks from 15–20 feet away

Covers nitrogen & process gas

Every leak tagged and sized

What We Inspect

Nitrogen and other process gas systems across the plant, using ultrasonic CTRL UL101 technology.

What We Find

Leaks that are invisible and inaudible to the human ear — a wasted generation cost and, in some plants, a safety risk.

How It Helps

Each leak is tagged, sized, and quantified so repair priorities are clear.

Our Advantage

The same proven ultrasonic technology behind our compressed air survey, applied to process gas systems.

A process gas leak is invisible, silent, and expensive — and in some plants, a safety risk long before anyone notices it, since the gases involved often have no smell or color to give the leak away on their own.

Process gas leaks — including nitrogen systems — waste generation cost and can pose safety risks. Using the same CTRL UL101 ultrasonic technology behind our compressed air survey, we locate leaks that are inaudible to the human ear and invisible to the eye, even from a distance of 15–20 feet, without needing to shut the system down to test it.

Each leak is tagged, sized, and quantified so repair priorities are clear, turning a scattered set of suspected weak points into a specific, ranked list your team can act on.

Gas Leak Survey — Frequently Asked Questions

What is industrial gas leak detection?

It's an ultrasonic survey that locates leaks in nitrogen and other process gas systems — leaks that are inaudible to the human ear and invisible to the eye, even from 15–20 feet away.

Why is gas leak detection important?

Process gas leaks waste generation cost and, in some plants, pose a safety risk long before anyone notices them.

How is gas leak detection performed?

Using the same CTRL UL101 ultrasonic technology behind our compressed air survey, engineers locate leaks and tag, size, and quantify each one found.

Which industries use this service?

It's used in chemical process plants and any facility running nitrogen or other process gas systems.

What information does the customer receive?

Each leak is tagged, sized, and quantified so repair priorities are clear.
