Stainless steel in the pulping process

Application of stainless steel tubes in sulfate pulping process in the paper industry

The sulphate pulping process is not as corrosive as the sulphite process. In this process, the wood floating in the sea, the use of saline water and chemicals (crystalline sodium sulfate, containing 0.3% Nacl) will make the process medium contains a certain amount of chloride, exacerbating the corrosion of the equipment. Practical experience has proved that 022Cr19Ni10-304L stainless steel tube and 022Cr17Ni12Mo2-316L Stainless Steel Tube can be used with satisfactory results.
