What is happening to the domestic steel pipe manufacturing equipment

Significantly increase of the level of domestic steel manufacturing equipment.

Representative steel companies
Tianjin Pipe's φ273mmMPM units (including Tianjin Steel Pipe φ426mm PQF units andφ159mm FQM CSST's crew) represents the world-class level of the most advanced equipment and rolling tube technology, especially PQF (FQM) continuous pipe mill represents the latest development of the current pipe mill and manufacturing processes. PQF (FQM) MPM can increase rolling tube wall thickness tolerances, improve the finished products rate, reduce tool consumption, and roll thinner wall steel pipe.

At the same time of the introduction of advanced pipe mill, also introduce a number of varieties suitable for the production of special units, such as Φ170mm of Daye seamless steel pipe. Tianjin Pipe's Φ219mm three roll pipe mill and Zhejiang Jiuli 3150kN squeeze tubes and other units. These units are also equipped with high level, has obvious advantages in the production of special thick-walled seamless steel pipe or high alloy varieties, production is also more flexible.

Baosteel UOE pipe unit, using proven internationally advanced technology and the most complete equipment currently, is the most advanced production equipment, production of the highest grade welded steel pipe production unit during the near two decades home and abroad. The construction of this pipe unit complied with the reality of rapid development of China's pipeline construction in recent years, laid a good foundation for the production of high grade LSAW steel pipe production required by the transition into the high grade large pressure pipeline.

Baoji Steel Pipe Company construction of coiled tubing production line is not only the first in Asia,but also the world's third coiled tubing production line, designed annual production capacity of 15,000 tons, product diameters from 25.4 to 88.9 mm, wall thickness of 1.91 to 6.35 mm, with broad market prospects. Completion of this production line fills the gap in the domestic pipe industry, marking the Baoji Steel Pipe Company achieved a new leap in product diversification.

With the improvement of steel unit level, China's seamless steel pipe and welded steel pipe quality and technical level has caught up with the international level, including obtaining the relevant certification, and now the shortcoming is the high class nuclear power tubes, including boiler tubes, precision tubes needed imported, but most of the country or to meet the needs of our own.
