Kadant Johnson releases rotary joint for steam or thermal oil transfer

Kadant Johnson, a subsidiary of Kadant Inc., has announced the ELSX rotary joint, which is designed to transfer steam or thermal oil into and out of rotating equipment.

The company says that the new design increases the reliability, durability and overall speed and pressure capability of Kadant Johnson extended-life joints.

In steam applications, the ELSX proprietary seal ring extends the life of the rotary joint by increasing the allowable seal wear while decreasing the seal wear energy. When used with thermal oil, the application-specific seal ring prevents leaks during break-in and offers high reliability. In both steam and thermal oil applications, internal support guides have been redesigned and enlarged to handle high-energy, high-vibration applications.

Steam applications have a maximum design speed, pressure and temperature of 300 rpm, 300 psig and 500 F, respectively. Thermal oil applications have a maximum design speed, pressure and temperature of 300 rpm, 150 psig and 650 F, respectively.
