The most advanced neural network identification technology in the world.
SL-5088PCM comprehensive inspection and evaluation system for external coating of buried pipeline is designed to provide guidance and help for pipeline industry. Suitable for corrosion and protection of oil, natural gas, city gas and underground water pipelines. However, due to the lack of early detection and diagnosis in pipeline network maintenance, it is impossible to effectively find the hidden danger that the pipeline section is not perforated but the anti-corrosion insulation layer is damaged and ineffective, which has become one of the reasons for the annual maintenance and perforation of buried pipelines. The protective layer of pipeline is aging, fragile, peeling and falling off due to long-term burial, which leads to corrosion and perforation of pipeline and incalculable losses due to leakage. SL-5088PCM can detect buried pipelines under trenchless conditions, realize the qualitative evaluation of the damage of the external coating of buried pipelines, and accurately locate and measure the depth of pipelines, thus solving the problem that it could not be detected under trenchless conditions before. By inspecting the protective layer of buried pipeline, replacing and repairing it pertinently, the service life of pipeline can be prolonged, which can save a lot of maintenance and reconstruction investment. It is very important to ensure the normal operation of the pipeline.

SL-5088PCM。 Comprehensive detection and evaluation system for external coating of buried pipeline. Working principle. This instrument consists of a transmitter and a receiver. The transmitter is an independent 0. 1A-3A detection signal output device, and the handheld receiver is used for pipeline route tracking, accurate location of damaged points and current measurement. The current intensity on the pipeline decreases with the increase of distance. Under the condition that the pipe diameter, pipe material and soil environment are unchanged, the better the insulation of the anti-corrosion layer to the ground, the less the current loss and the smaller the attenuation. On the other hand, if the anti-corrosion coating is damaged, such as aging and falling off, the worse the insulation performance, the more serious the current loss and the greater the attenuation. SL-5088PCM adopts the most advanced neural network identification technology in the world, which can quickly determine the size and direction of the damage point of the anti-corrosion coating, solve the worldwide problem of slow detection speed and high grounding requirements of similar instruments abroad, and make our detection instrument one of the advanced detection instruments in the world. This system is a patented product of China Jiangsu Shengli Instrument Company.
