The word “made in China” is widely known in the world. When we talked about “made in China” ten years ago, we would be very proud to tell the world our strength. But today, ten years later, we are telling the world that “made in China” is China’s real pursuit. And China is realizing it step by step. According to Xinhua News Agency, China can now complete the construction of a nuclear power plant in six years, thanks to a breakthrough in 2015.
By 2015, Qinghai’s 68000 ton extrusion and die forging dual-function heavy-duty press will extrude the world’s longest seamless steel pipe. This technology has successively invested more than 1.1 billion yuan. The first carbon steel seamless steel pipe is 12.8 meters long, 630 mm in diameter and 110 mm in wall thickness. This is the world’s largest and strongest ultra thick seamless steel pipe, which has come out earlier. In 2009, China was able to produce its own seamless steel pipes for nuclear power plants with smaller specifications. Most of the imports from the United States, Europe and Russia have been for a long time. It’s very dangerous to rely on imports for a long time in nuclear technology. Chinese researchers have long been I thought of this before. After more than ten years of technical research and numerous experiments, China has finally achieved 100% independent development of supercritical and ultra supercritical seamless steel pipes. It has become one of the most advanced countries in the world and started to export to developed countries such as Europe, which is a miracle China has created.
