Parameters: maximum pressure: 1.5MPa maximum temperature: 180 ° C maximum speed: 250rpm applicable fluids: coolant, hot water, cold water, compressed air, structural characteristics: this type of series rotary joint, according to the modern steel continuous casting equipment and specially designed 's. The same applies to other industries, especially the external installation size is limited. It is characterized by the majority of the connector into the inside of the roller, the outside only exposed pipe connection elbow, is conducive to the assembly arrangement of the external space, and more beautiful. This sealing structure, in addition to the balanced design, but also to be able to change the original axial tandem inverted concealed, so that, not only reduces the axial length, and the flange and the housing integrally, more conducive connector demolition installation and maintenance.
