According to the China Petroleum and Natural Gas Pipeline Administration (CPP), a national scientific research project was undertaken by the pipeline administration and a key international cooperation project of CNPC in the 11th Five-Year Plan, a 1016mm diameter high-definition pipeline magnetic flux leakage detector, was recently launched in Beijing. This is the first set of high-definition pipeline magnetic flux leakage detector in China, which fills the gap in the field of high-definition pipeline detection technology in China.
According to reports, 33 national patents and 105 proprietary technologies have been declared in the development process of this project, which marks that our pipeline inspection technology has entered the international advanced ranks. Experts said that the successful development of large-caliber and high-definition pipeline magnetic flux leakage detector has important milestone significance for guaranteeing national energy security.
It is understood that the large-caliber and high-definition pipeline magnetic flux leakage detector undertaken by CNPC Pipeline Detection Technology Co., Ltd. is a key foreign cooperation project with independent intellectual property rights of CNPC. It is based on the principle that a magnet generates a longitudinal loop magnetic field on the pipe wall to detect on-line the corrosion, external damage, metal loss and cracks in the inner and outer walls of the pipeline, and record the precise location of the defects, so as to facilitate the risk assessment, maintenance and maintenance of the pipeline, and carry out reasonable maintenance and integrity for the owners of the pipeline. Sex management provides scientific basic data and an important guarantee for the safe operation of pipelines. And it will not cause damage and pollution to the air, water and land along the pipeline, nor will it cause harm to the human body.
It is reported that the pipeline Bureau (CPP) plans to use the shortest time to realize the serialization of high-definition detectors in an all-round way. By the end of next year, eight sets of high-definition detectors with different calibers will be put on the market one after another, forming the equipment and technical advantages of "people without me, people with me, people with me, excellence, people with me" and improving our country. The comprehensive service capability of the pipeline inspection business will create "China Oil and Gas Pipeline 120".
