Steel Pipe Industry Development

1, the founding of New China, China is not the production of seamless steel pipe, 1953, China's Anshan Iron and Steel company introduced from abroad the first set of Φ140 automatic pipe mill production line put into operation after opened the era of China's own production of seamless steel tubes.
2, With the development of seamless steel pipe production in 1989, China's own design and manufacture, the introduction of seamless steel pipe more than 60 sets of units, design production capacity of over 200 million tons, of which more than 50 sets of Φ60 ~ of Φ100 unit, the production of small diameter accounted for more than half of the seamless steel pipe production, the fewer number of species, can not meet the needs of the community was forced to import large quantities of seamless mild steel pipe to supplement.
3, Beginning in 1998, China seamless steel pipe industry has entered a period of rapid development. From developed countries to introduce the MPM unit (MPM), retained mandrel three roller units (ie PQF), the Asser pipe mill (ie, Assel), Ake - Rolle pipe mill (ie the Accu-Roll) and our own design and manufacturing cycle pipe mill, automatic pipe mill, pipe jacking unit. At present, China has nine categories of 42 sets of hot-rolled tube unit, we can say is the most complete types and specifications of the world's hot-rolled tube unit is the world's hot-rolled seamless steel pipe unit Daquan, hot-rolled seamless steel pipe of the World summary of the most advanced unit, the base of the world's newest tube rolling experiment.

Seamless steel pipe enterprises to increase the intensity of technical transformation, the new unit soon production and deliver results, the rapid growth of China seamless steel pipe production, the production of seamless steel pipes from 415 million tons in 2000, increased to 18.63 million in 2007 t eight years, an increase of 4.5 times the average annual increase of 20.65%.
