Seamless steel pipe is known as the "blood vessel" of industry, is an important raw material for national industrial construction and national defense construction, whether it is the manufacture of aircraft, ships, trains, automobiles, boilers, or oil, steam, water, or the development of mineral deposits for geological drilling, where it is needed, where it is inseparable. It can be said that if you leave the seamless steel pipe, many industrial development such as petroleum, chemical, steel, machinery, military, aerospace and other industries will be out of the question.
In the early years of 1949, China could not produce seamless steel pipes. At that time, only Shanghai had a little steel pipe transformation equipment, but due to the lack of hot perforating machinery, it could not use round steel to produce seamless steel pipes, and it could not import capillary pipes from abroad, and it could only use imported or used old seamless steel pipes to change into other specifications of seamless steel pipes. Due to the economic blockade and embargo imposed by the Western hostile countries on the new China, the source of seamless steel pipes imported from abroad was interrupted, and at that time, the domestic production could not be produced, which had a serious impact on the recovery of the economy and the defense industry. From August 1952 to May 1953, China sent 40 people to the first Ural new steel pipe factory in the former Soviet Union to study. With the help of Soviet experts, the workers overcame technical difficulties.
On October 27, 1953, almost all the workers arrived at the factory early, nervous and excited. On this day, China's metallurgical history will open a new page. At 2:30 in the afternoon, the whistle ordering the hot test rolling sounded, the red billet was spit out of the 1200 degree high temperature heating furnace, and the hot red steel pipe head was just exposed in the piercing machine, and people cheered: "Out!" It's coming out! The pole is out!" All the people present applauded and cheered for this historic moment of rolling seamless steel pipes in New China. The steel pipe with sparks smoothly through the mill, another round of applause and cheers, until the first steel pipe to the last process. At this time, a Soviet expert shook hands with the workers present and said: "New China has its own seamless steel pipe from today!" Gu Fengfu, a young worker who had been to the Soviet Union to learn seamless steel pipes, said excitedly: "He will immediately write a letter to the Soviet teacher who taught him the technology." Another worker said: "When he goes home, he will also tell the farmers in the countryside that they and the people of the whole country have not supported Angang's construction in vain."
On October 27, 1952, the first tube billet test rolled out a seamless steel pipe finished product, which is also a miracle in the international seamless steel pipe business. Since then, the new China has its own industrial veins.
Anshan Steel seamless steel pipe plant put into operation, the end of China can not produce seamless steel pipe history. From the factory broke ground to the first seamless steel pipe came out, it only took 1 year and 3 months. The second year after production, it has been tested out, boiler tube, geological pipe, oil pipe and stainless steel pipe. The success of rolling stainless steel pipe on the two-high skew piercing machine is a great event in the history of seamless steel pipe production in our country, which plays a forerunner for the future production of stainless steel pipe in our country.
