As much as now, the existing domestic seamless steel tube production gear level is uneven, both in backward along with the most advanced. The early building of slitting line of hot-rolled seamless fur and arakawa tube gear is somewhat basic, with backward technology, higher consumption also as really serious pollution, its production are about to be stopped , but there's still some parts in half a quit and half a ajar. following adjustment and reform, some equipment are applied specifically for the production of a single species, for example bearing tube of general objective, low and Steel pipe mill for sale
, structural tube and fluid pipe, and so forth. According to the specifications of varieties and top quality specifications and its positioning, the forming line of it has been adjusted and transformed to decrease the investment, consumption and the expense of sophisticated technological process.
The representative of Steel pipe mill
primarily contains rolling unit, precision tube rolling unit, 400 mm automatic tube rolling unit, three roll pipe unit and Higher frequency welder and so on, amid each of the equipment level of the units, some are rather sophisticated, reaching an international level, which include the domestic 108 3 roll pipe unit, which was the experimental units began to design in 1968,and was by way of the experiment and attempt rolling in 1979 , by means of the identification in 1980, ministered and approved in 1984 and was completed and put into operation in 1987, ultimately completed the renewal and reconstruction in 2002, with its gear level towards the highest levels on the present 3 roll pipe units. The entire unit might be in totally automatic operation by pc, or artificially operated alone. Besides, the domestic 102 pipe jacking unit, completed and place into operation in 1988, is inside a larger level of pipe jacking unit in the 1980 s with its electric drive manage unit gear, instrument and instrument measurement also as adjusting chain operation manage method.
At present our nation is among the greatest world's unit group corporations with the most kinds and specifications of hot-rolled tube unit, as well as the most recent and most advanced hot High frequency components
, also could be the world's sample plot of the newest gear and sites in the units. In accordance with the incomplete statistics, China's several current welded steel pipe mill has reached almost 1 thousand sets, amid the complete, the domestic two roller units are more than 300, and much more roller sets happen to be greater than 600, at the same time as 43 sets of your imported units.
