At that time, there was an imbalance in the overall professional development of stainless steel pipe fittings in China. At the time when the output value of stainless steel pipe fittings increased sharply, the source of the blanks was very serious. It is difficult for the company to produce and operate. In addition, the primary technical and economic goals need to be further improved. The yield rate of hot-rolled steel products (slab-stock) in China is around 93%. Meanwhile, the yield rate of hot-rolled seamless stainless steel pipes (blank-stock) depends on the level of technical equipment. The same fluctuates a lot. Skills leading rolling mills are usually 90-92%; skills lagging mills are only about 80%; leading mills are more than 75%, and lagging mills are less than 70%. In short, the above goals are still far from the international leading level, and they need to be improved urgently. , To improve the competitiveness of stainless steel pipes, it is necessary to improve production skills, and deal with the origin of the blank material. Only in this way can the steel pipe profession go further.
