In order to enter the nuclear power market, sea salt fasteners accelerate the upgrade

In order to speed up the upgrading of fastener products and broaden the application fields and market prospects, Haiyan County Quality Supervision Bureau applied for and implemented seven scientific research projects approved at various levels on the basis of last year, and applied for seven scientific research projects this year. There are 1 General Bureau, 2 Provincial Bureaus and 4 Provincial Science and Technology Departments.

In 2009, the implementation of the key product quality catch-up project in Zhejiang Province "The quality of screw thread spikes in high-speed railways surpassed the international advanced level". Zhejiang Haitaike Standard Parts R & D Co., Ltd. uses new materials and new processes to develop high-strength fastener products and successfully developed them. For high-speed railway screw spikes at a speed of 350 KM/H, the product's technical indicators have reached the international advanced level, and passed the quality certification of German VOSSLOH company and the testing of the National Standard Product Quality Supervision and Inspection Center, which changed the dependence of the product. Imported situation, to achieve product localization. Zhejiang Qifeng Standard Parts Co., Ltd. has taken over orders for 70 million yuan and has already completed 60% of orders for production. The products have been supplied to the 300-type fastener system of VOSSLOH in Germany and have been successfully used in major domestic projects such as the Wuhan-Guangzhou Passenger Line, the Zhengzhou-West Passenger Line, and the Beijing-Shanghai High Speed ​​Rail.

In order to enter the nuclear power fastener market, Haiyan County Quality Supervision Bureau and Zhejiang New Oriental Fasteners Co., Ltd. jointly declared the province's quality catch-up project “The quality of welding studs to surpass the advanced level of the nuclear class” this year. At present, the material selection and mold surface have been completed. Modification technology research. The implementation of the project will realize the localization of nuclear welding nails and at the same time enhance the level of the company's supporting sea salt nuclear power industry. The above two projects are all domestically made alternative imports. In addition to economic benefits and political benefits, they also provide demonstration and promotion for the upgrade of sea salt fastener products.
