Product Introduction

YH-PED1  Inteligent Pipeline Comprehensive External Inspection System is a high-performance inspectin equipment that integrates the evaluation function of the external anti-corrosion layer of buried pipelines and the effectiveness inspectin and evaluation function of cathodic protection of external pipelines. This system has developed a new inspectin mode, which integrates high-precision GPS (RTK) module, Bluetooth module, and wireless data remote transmission function (in conjunction with mobile APP). With just one tap, it can complete the collection of various data such as pipeline positioning, pipeline burial depth, ACVG, ACAS, CIPS, DCVG, IR%, GPS coordinates, GPS clock, mileage, etc. The inspectin data can be transmitted in real time to the remote data monitoring and processing software platform. This not only solves the problem of interference between PCM/DM inspectin systems and CIPS/DCVG inspectin systems that cannot be detected simultaneously, but also achieves accurate alignment of pipeline geographic information data, anti-corrosion layer inspectin data, and cathodic protection inspectin data. This system greatly improves inspectin efficiency, accuracy, and availability of inspectin data by optimizing the on-site inspectin process and post data processing process, effectively reducing the labor intensity and technical level requirements of on-site inspectin personnel.

1. Integrated pipeline comprehensive surveying and mapping function

① Based on the centimeter level GPS (RTK) module, high-precision pipeline geospatial information data collection and visualization graphics such as pipeline routing maps, elevation maps, and burial depth maps can be completed by combining the longitude, latitude, elevation, and pipeline burial depth data of positioning points with GIS geographic information systems;

 

② Integrating ACVG and DCVG inspectin functions, two testing methods can be used simultaneously to locate the defect points of the external anti-corrosion layer of the pipeline, and real-time display of parameters such as dB value, IR% value, and corrosion activity of the defect points of the anti-corrosion layer;

 

③ Real time display of 4Hz near DC current and 128Hz/640Hz positioning current values, using AC current attenuation method (ACAS) to evaluate the insulation performance of pipeline anti-corrosion layer;

 

④ Integrated CIPS inspectin function, the transmitter and receiver come with GPS/RTK modules, compatible with various on/off devices such as DCVG company, CATA-TECH company, Yahe IHF constant potential meter, etc. In the synchronous on/off mode of the transmitter, receiver, and cathodic protection power supply, real-time display of pipeline on/off potential and evaluation of pipeline cathodic protection level.

 

2. Accurate alignment of inspectin data

Based on the integrated pipeline comprehensive surveying and mapping function, it solves the industry pain point of various external pipeline inspectin methods interfering with each other, multiple inconsistent tread paths, and ineffective alignment of various inspectin data in the past. A single tread can achieve synchronous collection and one-to-one correspondence of multiple inspectin data such as GPS, ACVG, ACAS, DCVG, CIPS, etc., achieving precise data alignment and improving the accuracy and reliability of inspectin data.

 

3. Optimized inspectin process.

In the past, the ECDA external inspection process for pipelines was cumbersome, with many inspection equipment and accessories, requiring multiple threading to complete all external inspection work. The Yahe Intelligent  Inteligent Pipeline Comprehensive External Inspectin System integrates multiple inspectin functions and optimizes the on-site inspectin process through a new inspectin mode. The inspectin equipment can achieve single person weight bearing, and the inspectin data can be stored in the inspectin host or wirelessly transmitted to the remote data monitoring and processing platform. The platform can display various types of inspectin data in real time, and through optimized algorithms, it can achieve automatic processing and auxiliary analysis of inspectin data. It has the function of automatic alarm for abnormal data, which can timely detect problems at the inspectin site and take action.
