Our jacket steel dry cylinders series are mainly used for specialty paper industry, is the key part of paper-making machinery with a single or double cylinder.    
The series jacket cylinder uses interlayer structure. Steam recycles only around the narrow space of external cylinder -and the unique design of the drain system, which reduce the energy consumption and production cost. The core shaft and cylinder shell use the interference assembly, stable rigidity greatly prolong the service life. Based on the paper quality, it can use chrome plating or spraying etc for surface.
