At present, the rapid growth of the petroleum industry is increasing the demand for installing fuel transportation pipelines. As a result, the risk of pipeline leakage — which may be caused by human factors or natural conditions — has become a major challenge for the oil and gas sector.
Early leak detection helps prevent serious incidents that could lead to greater damage and also reduces operating costs. Currently, NLT Group has developed an integrated solution

Oil & gas fire protection & toxic gas leak detection system, using ultrasonic leak detection technology. Its effectiveness and accuracy are demonstrated through inspection without requiring direct physical contact with the pipeline. They are ideal for hazardous / hard-to-access environments where safety is critical.
NLT Group specializes in the installation of toxic gas leak warning sensor systems for the oil and gas industry for fire protection equipment rooms, fuel storage warehouses, oil refineries, … Design and installation solutions are carefully developed and appropriately tailored to real-world conditions.

Operating principle of the oil & gas fire protection & toxic gas leak detection system

The NLT hazardous chemical leak warning system operates with a simple, effective, and safe mechanism. When an oil leak incident is detected by the sensor, the signal will be transmitted to the sensor controller. Then, the signal continues to be sent to the main control panel for processing and issuing alerts simultaneously to the unit’s monitoring system (PC), on-site devices (PCL, DCS System), and warning lights. See the detailed diagram below.
