Product Description

The M81 series rotary joint is designed according to the characteristics of the roller of the continuous casting machine, which penetrates most of the joint shape into the inside of the roller and exposes the pipe connecting flange, the utility model is favorable for the space arrangement between the flow of the roller table and the flow. The seal structure design of the rotary joint adopts the balance type mechanical seal design, the seal element is high temperature resistant, wear resistant material, changes the original axial series type, is the unique inverted internal seal type, thus, not only has reduced the axial length, and make the shell structure into a whole, more conducive to the joint disassembly and maintenance.
