Rotary Joint Applications - Full steam ahead!
A rotary joint, also referred to as a rotary union or rotating union, permits the flow of various media from a supply pipe in to and/or out of rotating equipment. Heat transfer and hydraulic media typically used with this equipment include steam, water, thermal oil, hydraulic oil, air, and coolant. It is worth the time to evaluate new applications as well as existing applications to ensure the right rotary joint is used. The critical application information includes:
- Fluid type (steam, water, air, etc.)
- Rotational speed
- Pressure
- Temperature
- Flow Rate
- Piping and equipment connection sizes
Selecting a rotary joint from a catalog can be suitable for some applications, but many require a more detailed engineering evaluation. Kadant Johnson leverages proprietary tools and extensive application expertise to analyze flow capacity, pressure drop, and expected seal life under actual operating conditions. Based on this analysis, the optimal rotary joint and seal technology are recommended to match the specific demands of the application.
For existing installations, we compare actual field performance to expected results. If reduced efficiency or shortened service life is observed, it may indicate the need to reassess the application. While equipment can operate at the upper limits of its design range, performance typically declines when multiple limits are approached simultaneously. Changes in operating conditions, such as increased speeds, higher temperatures, or production demands, can also make a previously suitable rotary joint less effective.
Custom Rotary Union Solutions
Some applications are better suited for a custom solution or a rotary joint with a different configuration. For these applications that require specialized solutions, our engineering team focuses on providing technology that meets the application demands. Your goal is our goal, and we work closely with you to develop reliable, efficient, and technically advanced products that add value by improving the process and the quality of the end product.
