company news about China's Pride: The Largest Heavy Extruder For Seamless Pipe In The World

 National interest, National strength and National pride 

Breaking the international monopoly, China has become the world's largest owner of the technology and design of the vertical extruder for large caliber thick wall seamless tubes

China is a large energy consumer, and there is still a huge energy shortage. To meet China's energy shortages, it will need to build large quantities of thermal and nuclear power plants. Large-caliber thick-walled seamless pipe is an essential material for thermal power, nuclear power and other energy equipment, a core material for key components of high-end equipment.But the large caliber thick wall seamless tube needs the heavy duty extruder to manufacture. Previously, because only Germany, Japan and USA had the mature extrusion technology and equipment, China has been subject to their high prices or outright refusal to transfer the technology.

China in the case of foreign blockade technology, Rally the nation strength, lead by Shi Changxu, academician of the Chinese academy of sciences, forging experts such as Yan Yongnian, and scientists such as Lin Feng etc, jointly research and developed by Tsinghua University, Shenyang heaving forging 447 plant, and the Changcheng special steel, finally developed with international competitiveness of the world's largest vertical extruder, with technology and product quality to create the world class. The main equipment of the extruder is less than 4,000 metric tons, which is more than two-thirds lighter than the 14,700 tons of NISMA extruder developed in Russia. It can produce OD1320mm, maximum wall thickness of 300mm heavy seamless tube, which suitable for high temperature alloy, stainless steel, alloy steel, carbon steel, nonferrous alloy and other materials, to meet the demand for special materials and ultra-large products for application of thermal power, nuclear power, petrochemical, aerospace and military industries etc.
