Goldhome Hipot Advances Underground Pipeline Inspection with Intelligent Detection Technology
Wuhan Goldhome Hipot Electrical Co., Ltd. continues to drive innovation in the field of electrical inspection equipment through its professional intelligent pipeline inspection system. This device provides reliable solutions for public utility companies and municipal services responsible for maintaining underground pipeline infrastructure.
The intelligent pipeline inspection system represents a major innovation in non-destructive testing technology. Utilizing advanced detection principles, it enables operators to locate underground pipelines, assess their condition, and identify potential issues without excavation. This capability helps prevent service interruptions and reduces costs associated with traditional inspection methods.

Basic Components
Basic Kit: The standard configuration basically consists of a transmitter and a receiver. The transmitter is responsible for transmitting specific detection signals and usually runs on batteries. For example, some models have a 3.7 V lithium-ion battery. The receiver has components such as a 3D antenna, high-resolution touch screen, and Bluetooth module to capture and analyze signals. Some high-end receivers additionally offer backlit screens and vibration alerts to adapt to various working environments.
Accessories: In addition to the basic components, numerous accessories are also provided. Common accessories include current clamps for signal connection, flexible current clamps adaptable to different pipe diameters, and test cable connectors. Optional accessories such as Type A brackets are available for specific scenarios like fault location. Some models also feature waterproof probes to meet detection requirements in humid environments.
Operating principle
Electromagnetic induction principle: This is the most commonly used principle for detecting metal pipes. The transmitter applies a specific frequency detection signal to the underground metal pipe via direct connection, induction, or coupling. Once the pipe causes a signal loop, the receiver captures the signal and analyzes parameters such as signal strength and phase to determine the location and depth of the pipe.
Magnetic flux leakage and ultrasonic principles: For internal pipeline inspection, some smart detectors use magnetic flux leakage (MFL) technology. By locally magnetizing the pipeline, magnetic flux leakage occurs where there are defects such as corrosion in the pipe wall. Sensors detect this leakage to assess the condition of the defect. Ultrasonic testing (UT) is applied in a similar manner for internal pipeline inspection, allowing for accurate identification of defects on both the inner and outer surfaces through the transmission and reception of ultrasonic waves.
Key Features
High Detection Accuracy: It delivers exceptional positioning and depth measurement precision. For instance, the PL-G07 Smart Pipeline Detector achieves positioning accuracy of ≤±2 cm at 1.2 meters depth and ≤±5 cm at 2 meters depth. Generally, traditional models offer positioning accuracy of ±5% at burial depths of 0 to 3 meters and ±10% at 3 to 15 meters, meeting most engineering detection requirements.
Strong Adaptability: Supports multiple active detection frequencies. For instance, the Japanese Fuji PL-G detector offers three frequencies: 27kHz, 83kHz, and 8kHz. The transmitter can even emit two frequencies simultaneously, making it suitable for detecting pipelines with different diameter combinations. Additionally, it operates within a wide temperature range, typically covering 20°C to 50°C, and can function continuously for over 8 hours, facilitating field operations.
Smart Data Processing: Many high-end models integrate Bluetooth and even GPS modules. They can transmit detected pipeline coordinates, burial depth, and other data in real-time to mobile applications or ground control centers. Upon completion, they automatically generate data tables for subsequent sorting and analysis, and support integration with GIS systems to map pipeline layouts.
Industry Applications
Municipal Infrastructure Maintenance: Used in urban road construction and new area development to survey underground water supply, natural gas, and communication pipelines. It marks the precise location and burial depth of pipelines to prevent damage during excavation. It also locates leaks in municipal water supply and drainage pipelines, as well as corrosion points in gas pipelines, ensuring the normal operation of urban public facilities.
Petroleum and Chemical Industry Inspection: Used to inspect long-distance oil and gas transmission pipelines and subsea pipelines. By employing techniques such as magnetic flux leakage, it rapidly detects wall thinning and corrosion in pipelines, providing maintenance recommendations to prevent major safety incidents like oil and gas leaks.
Power and Telecommunications Pipeline Management: It assists power and telecommunications departments in locating underground cable routes and identifying target cables among multiple parallel lines. It also precisely pinpoints cable fault breaks, reducing maintenance complexity and shortening repair times.
