In many regions, however, pipelines face a serious threat: illegal tapping.
Illegal tapping occurs when someone drills into a pipeline to steal the product inside. The hole may appear small, but pipelines carry fuel under pressure. Even a tiny pe*******on can quickly turn into a leak, fire, or explosion, putting nearby communities, workers, and the environment at risk.
Because of this, operators cannot rely on assumptions about pipeline safety. They need precise inspections.
One technology used to detect these threats is Direct Magnetic Response (DMR).
DMR tools travel through the pipeline while it is still in operation. As the tool moves, magnets and highly sensitive sensors scan the steel pipe wall. When the pipe is intact, the magnetic field behaves normally. If a drilled hole or pe*******on exists, the magnetic field changes. The sensors capture these changes and record their location along the pipeline.
What makes DMR especially valuable is its ability to detect very small drilled holes. Illegal taps are often made using basic drilling tools, creating holes only a few millimeters wide. Many traditional inspection technologies focus mainly on corrosion or large damage, meaning these tiny pe*******ons can sometimes go undetected.
Detecting them early is critical.
A drilled hole weakens the pipe wall. If it is poorly sealed, pressure, vibration, or corrosion can make the damage worse over time. What begins as theft can eventually lead to leaks, fires, or catastrophic failure. This is why every detected tap matters.
Topline Limited has deployed this advanced DMR inline inspection technology across four pipeline locations in Nigeria, covering more than 130 kilometers of pipeline. During these runs, over fifteen illegal taps were identified for clients, allowing operators to locate and remove unauthorized connections before they developed into larger safety or operational risks.
Topline Limited maintains exclusive deployment rights for this proprietary DMR inspection technology within the Nigerian market.
Pipelines may be out of sight, but the risks around them are real. Technologies like DMR allow operators to detect hidden threats early, helping protect infrastructure, communities, and the steady flow of energy that modern life depends on.
