Paper making equipment

Application of special alloys in the field of papermaking equipment:        In life, paper is an indispensable cultural item for human beings and has a wide range of uses in daily life, learning, and work. The appearance of paper has promoted the progress of human civilization; it has changed human life and brought great convenience to mankind.        In the process of papermaking, a large amount of heavily polluted sewage or waste residue from the papermaking process will be produced. Stainless steel industrial pipes have the characteristics of corrosion resistance and resistance to chloride corrosion. Therefore, stainless steel industrial welded pipes play a great role in the sewage discharge of the papermaking industry.        In order to promote the concept and practical experience of low-carbon papermaking and promote the development of China's paper industry to a green industry, stainless steel industrial welded pipes also play a large role in the reduction of sewage and emissions. When many paper companies build new plants, they will apply to stainless steel industrial welded pipes . In the field of pulp and paper industry, the domestic market is almost blank. The kraft cooking method still uses low-carbon steel cooking pots, and the use of duplex stainless steel cooking and bleaching equipment has been widely used abroad. Very little.         Commonly used in high-concentration chloride ion environment of various bleaching devices, scrubber drums, pressure rollers, tanks, pipes, digesters in pulp bleaching systems.
