Recently, the domestic testing equipment with the widest range of diameters and the highest detection accuracy of metal tubes for on-line automatic detection has passed the identification at the Laser Research Institute of the Shandong Academy of Sciences. The successful development of this equipment has broken the monopoly of non-destructive testing equipment for metal pipes abroad, and the equipment price of the same indicator is only half of the imported equipment, and the advantages of substituting for import are obvious. Its application can boost the domestic metal pipe to the high-end market. The attention and welcome of major domestic steel companies.
China is the world's largest producer of metal pipes. There are more than 2,000 large and small metal pipe enterprises with an annual output of nearly 100 million tons, of which nearly 30% are exported. Due to the lack of mature detection technology and equipment in the country, high-priced foreign equipment often fails to adapt to the domestic complex production environment, resulting in most domestically-made pipes being low value-added structural pipes and low-pressure fluid pipes, making it difficult to enter the international high-end market. The National Development and Reform Commission proposed that China's steel industry should improve the quality of its development. From the major steel pipe producing countries to the strong steel pipe producing countries, the development of on-line non-destructive testing comprehensive technology and complete sets of equipment suited to the national conditions has become an urgent need of the industry.
The Shandong Provincial Academy of Sciences is supported by a major project of the province's independent innovation achievement transformation. This complete set of equipment developed independently uses eddy current and ultrasonic detection technology to achieve high-speed on-line detection of surface defects and internal defects of metal tubes. The diameter can be detected from 5mm to 1200mm. Basically covers all the specifications of the current domestic metal pipe, the detection accuracy meets or exceeds the international and domestic API, ASME, GB and other international standards, solves the problem of automatic online detection technology, has reached the international advanced level and has completely independent intellectual property rights.
Experts believe that the R&D and promotion of this equipment will drive the progress of detection technology in the entire industry and increase the international competitiveness and application of domestic pipe in high-end areas such as nuclear power plants, high-pressure boiler tubes, aerospace pipe, petroleum and natural gas pipelines, and so on. Product quality and added value to promote industrial upgrading. At the same time, the improvement of the quality of metal pipes can reduce the incidence of accidents in high-risk situations caused by cracking, leakage, and explosion, and improve the quality of economic operations. For the application enterprise, through the real-time detection of this equipment, it can analyze the causes of the disability of metal pipes and rods, adjust the production equipment in time, increase the product qualification rate, save a lot of energy and raw materials, and save significant profits.
Xu Hua, a researcher and director of the Institute of Lasers, told reporters that due to these good application characteristics, the equipment has received attention and welcome from major domestic steel companies once it is promoted. The complete set of equipment was successfully applied to Shanghai Baosteel through international bidding, and later promoted to more than 120 companies in more than 10 provinces including Baotou Steel, Panzhihua Iron and Steel, and Datang Power, and it has been established in Jiangsu Zhenda Steel Pipe Group Co., Ltd. and Linyi Shengyuan. Seam Steel Pipe Co., Ltd. is built as a demonstration project. At present, about 200 sets have been promoted, and each equipment has an annual inspection of 25,000 tons of metal pipes. After testing, the price per ton can increase by more than 1,000 yuan. Each year, new direct economic benefits for the application companies increase by more than 5 billion yuan, saving nearly 100 million yuan in raw materials and energy. Yuan, the product is in short supply.
