My metal pipe online automatic detection of complete sets of equipment instead of imports

On the morning of August 23, the reporter learned from the Institute of Laser Research of the Shandong Academy of Sciences that the automated online metallurgical testing equipment developed by the Institute was successful in its application. This equipment not only breaks the monopoly of foreign non-destructive testing equipment in China, but also adds direct economic benefits of more than 5 billion yuan each year for the application enterprises.

China is the world's largest producer of metal pipes, with more than 2,000 large and small metal pipe enterprises and a single production of nearly 100 million tons. Due to the lack of mature detection technology, it is difficult for products to enter the international market. At the same time, the testing equipment imported from abroad is not only expensive, but also does not adapt to the metal pipes produced in China.

In order to solve the problem of the online automatic detection of metal tubes in our country, the Laser Research Institute of Shandong Academy of Sciences launched a technological research. They achieved real-time on-line inspection of surface and internal defects of metal tubes by using detection techniques such as through-type, point-type eddy currents, water immersion, and water film ultrasonics. The automatic test equipment can analyze the cause of metal pipe's disability, remind production enterprises to adjust production equipment in time, and can remove the disability metal pipe from the production line at any time, which greatly improves the qualified rate of the product. The equipment can detect metal tubes with a diameter of 5mm to 1200mm, covering all the specifications of current domestic metal tubes. It is currently the most widely used metal tube online detection equipment with the highest detection accuracy, and has reached the international advanced level.

The director of the institute, Xu Hua, said that this equipment can not only replace imported products, but also the price of equipment with the same index is only one-half that of imported equipment. According to incomplete statistics, the equipment has been extended to more than 10 provinces such as Shandong, Jiangsu and Hebei. Nearly 200 sets of equipment have been applied by more than 120 companies such as Baosteel, Baotou Steel and Panzhihua Iron and Steel, adding direct economic benefits to these companies each year. More than 5 billion yuan, saving nearly 100 million yuan in raw materials and energy.

According to industry experts, the successful application of metal pipe online automatic detection technology has boosted the quality of domestic metal pipe materials, expanded the application of nuclear power pipes, high-pressure boiler tubes and other high-end fields, and will have tremendous economic and social benefits.
