[Case] Measuring the main bearing bushing of the mill with a thickness gauge

2019-04-28

There are 14 ball mills of various models in our factory. The main bearings of the mill are made of bearing alloy (Tungsten gold for short). In the past, we measured the thickness of tungsten gold linings by using an electric drill to drill small holes. This method of measurement is troublesome, and the depth of the hole is difficult to grasp. If the control is not good, the cast iron ball will be drilled. Ultra-small digital ultrasonic thickness gauges can quickly and accurately measure the thickness and internal defects of tungsten gold lining. Especially during the overhaul period, it is necessary to understand the raw material grinding, c......

[Case] Research on detection technology in pressure pipeline

2019-04-28

In recent years, China's economy has developed rapidly. With this, science and technology have also developed to a new stage, and the ultrasonic detection technology of pressure pipelines has developed. In addition, the aging problem of pipelines is becoming more and more serious. The integrity of oil and gas pipelines in operation and management process is greatly threatened. The more important one is the internal corrosion problem in pipelines. Therefore, accurate measurement of the inner wall information of the pipeline can contribute to the improvement of pipeline maintenance efficiency, and at the same time, can accurately predict the li......

[Case] Development status of in-pipe inspection technology and standard system

2019-04-28

China's oil and gas pipeline industry has achieved leap-forward development, and pipeline body defects and corrosion problems should be taken seriously. The oil and gas pipeline has fully enforced the integrity management procedures. The in-pipe inspection technology can determine the corrosion and crack defects of the pipeline and ensure the long-term operation of the pipeline. The system expounds the scope, advantages and disadvantages, technical status and application of the internal detection technology widely used in pipelines at home and abroad, including deformation detection, magnetic flux leakage detection, ultrasonic detection and e......
