When working with underground utilities, relying solely on a standard metal detector may lead to detection challenges. The reality of modern infrastructure is that more and more pipelines are being laid using non-metallic materials like PVC, HDPE, or fiberglass. 

 

These materials are great for resisting corrosion, but they are not detectable by traditional magnetic or electromagnetic locating tools unless tracer wires, metallic components, or specialized locating methods are present. This is where non-metallic pipe locators become essential. They bridge the gap in technology, providing the precise detection needed for safe excavation and long-term maintenance.

 

At RJM Company, we don’t just supply equipment; we provide tools designed to support accurate detection. We focus on providing advanced non-metallic pipe locators for contractors, engineers, and surveyors who want more reliable detection than traditional methods.

Challenges of Locating Modern Pipelines

​

In the past, almost every pipe was made of iron or copper. You could wave a simple wand over the ground, and it would beep. Today, water, gas, and sewer systems have moved to high-density plastics. Traditional metal-detecting tools may not detect modern plastic pipelines effectively, so specialized equipment is often recommended for more accurate location.

 

Damaging a plastic gas main or high-pressure water line can lead to potential safety concerns, project delays, and repair costs.

 

Using a specialized locator allows a crew to:

 

Pinpoint plastic mains: Finding exactly where the PVC or HDPE lines are buried.

 

Avoid "blind" digging: Reducing the risk of hitting a service line that isn't on the old city maps.

 

Streamline the schedule: No more hand-digging for hours just to find one stubborn pipe.

 

Verify depth: Many modern locators can provide approximate depth estimates under suitable site conditions.

​

Applications: From Municipal Work to Industrial Plants

​

Non-metallic pipes are everywhere now. We see our non-metallic pipe locators being deployed in almost every sector. Municipalities use them to map out aging sewer systems that were replaced with PVC decades ago but never properly recorded. 

 

Industrial facilities use them to track process piping that carries chemicals that may corrode metal but are compatible with fiberglass materials. Construction teams near high-density utilities use these locators as a "second set of eyes" to supplement utility markings provided through One-Call (811) systems.

 

In every case, the goal is the same: gather the facts before you put a backhoe bucket into the dirt.

Technical Features That Drive Accuracy

​

The FG155C non-metallic pipe locator is designed to provide precise detection of water pipes, whether metallic or non-metallic, using Acoustic and Radio Frequency technology. Its advanced tools include the Stopper, Striker, and High Power Locator Transmitter, designed to provide high-accuracy detection for underground pipe locating.

 

Stopper – Water Pulse Detection

 

• Creates water pulses on pipes up to 220 psi.

 

• Locates water pipes of all materials by tracking the sound pulses.

 

• Compatible with Sewerin or other water leak detectors for precise detection.

 

Striker – Tapping Detection

 

• Locates all pipes 2” and smaller, including water service lines.

 

• Tracks the tapping sound on the pipe with a water leak detector.

 

• Remote control allows pausing/starting and adjusting strike intensity for controlled detection.

 

High Power Locator Transmitter

 

• Provides up to 50 watts of power in pulse mode and 25 watts continuous.

 

• 120V output allows deeper and farther locates, reducing reconnection points.

 

• Offers 15 frequencies including 5 custom options: 512 Hz, 640 Hz, 1.1 kHz, 8.192 kHz, 9.995 kHz, 32.768 kHz, 41.66 kHz, 65.536 kHz, 83.078 kHz, 116 kHz.

 

• Supports induction at 9.95 kHz or 41.66 kHz for versatile applications.

 

Sewerin Utility Locator Receivers

 

• Complement the FG150 and FG150C to detect underground utilities efficiently.

 

Radio Frequency Detection – FG155G

 

• Sends a strong radio frequency for locating metal pipes or pipes with tracer wires.

 

• Ensures faster locates on challenging pipe types.

 

Acoustic Listening Devices

 

• Sewerin Stethophon 04, T10, A50, A150, A200 detect sounds from Stopper and Striker.

 

• A150 displays maximum levels at the current and two previous listening points.

 

• A200 displays maximum for pipe locating or minimum for leak locating across the current and seven previous points.

 

• Digital recording on A200 allows replaying and comparison for faster, more accurate pinpointing.

 

With these technical features, the FG155C and associated equipment deliver precision, flexibility, and reliable detection in a wide range of underground locating applications.

Saving the Budget and the Reputation

​

Hitting a pipe can be costly in repairs and may impact your professional reputation. Using proper detection equipment helps minimize such risks.

 

Using non-metallic pipe locators supports a more proactive approach. It can help identify the path of utilities, reduce exploratory digging, and assist in maintaining project timelines.
