Railway sleepers, also called railroad ties, railway ties or crossties, are an important railway component.
Generally, the rail sleeper is always laying between two rail tracks to keep the correct space of gauge.
Types of Sleeper :
Concrete sleeper
Woodern sleeper

The heat exchange component is a key component of the high-temperature gas-cooled reactor steam generator. The structure is complex and requires high precision, and the structure is the world's first design. The entire equipment is independently designed by the Nuclear Research Institute of Tsinghua University and has complete independent intellectual property rights. At present, the equipment has applied for or authorized more than 30 international and domestic patents, and the entire structural design has been applied for international patents in 15 countries.
On this basis, Jiangsu Yinhuan Precise Steel Pipe Co., Ltd. undertook the task of manufacturing multi-end spiral heat exchange tubes and heat exchange components. According to Zhuang Jianxin, founder of Jiangsu Yinhuan, the total investment of the heat exchanger assembly of high temperature gas-cooled reactor steam generator is 125 million yuan. It has now formed an annual production capacity of 228 sets of heat exchange components, meeting the requirements of two sets of 600MW high temperature gas-cooled nuclear power station steam The generator needs to achieve a large-scale and efficient industrial manufacturing of heat exchange components, and gradually form the supply base of high-temperature gas-cooled reactor steam generator heat exchanger components.
“Since the company established the HTR heat exchanger tube project department in 2006, it has overcome the 60-meter long tube straight tube manufacturing, multi-end spiral tube bundle forming, straight tube and spiral tube transition section space bending technology and equipment. After many technical problems, he obtained a number of invention patents and proprietary technologies and formed a batch production capacity.†Chairman of the company Zhuang Jianxin said, “Good technical accumulation has laid a solid foundation for the project's R&D and production.†The only nuclear tube manufacturer in 2014, the company invested 125 million yuan to start the industrialization project of high-temperature gas-cooled reactor steam generator heat exchanger components, and has now formed an annual output of 238 sets of heat-exchange module manufacturing capabilities to meet two 600MW Demand for steam generators in high temperature gas-cooled reactors. At present, the first phase of the project has been fully completed. In August this year, the delivery of all 38 components will be completed.
The reporter learned that the high-temperature gas-cooled reactor technology is one of the advanced nuclear energy technologies planned for the initial establishment of the national "863" plan. According to Wu Lanxin, head of the steam generator project of the Nuclear Energy and New Energy Technology Research Institute of Tsinghua University, the heat exchange component is a key component of the high-temperature gas-cooled reactor steam generator. The structure is complex, the precision is extremely high, and the structure is the world's first Design, there is no reference to the manufacturing process.

[China Instrument Network Instrument Research and Development] Recently, the key component of the fourth-generation nuclear power plant steam generator, developed independently by the Institute of Nuclear Energy and New Energy Technology of Tsinghua University, has been successfully developed and successfully put into production. The heat exchange components will be used in China's high-temperature gas-cooled reactor demonstration power stations with independent intellectual property rights, and the first products have been successfully produced. "It is expected that by August this year, all 38 sets of heat exchange components will be delivered. This batch of products will be used in China's own high-temperature gas-cooled reactor demonstration power plant with independent intellectual property rights. This is also the world's first fourth-generation nuclear energy system with safety features. The commercial demonstration reactors, said Zhang Zuoyi, dean of the Nuclear Energy and New Energy Technology Research Institute of Tsinghua University and the chief designer of the high-temperature gas-cooled reactor demonstration power plant, indicate that the steam generator heat exchange components are manufactured to achieve technological breakthroughs and have industrialization conditions.
