Rotary unions and rotary joints are essential components in steel and metal processing plants, enabling the reliable transfer of cooling water, hydraulic oil, air, and other process media from stationary pipelines to rotating equipment. They are widely used in continuous casting machines, ladle turrets, turning tables, rolling mills, and other critical applications — ensuring efficient operation, enhanced reliability, and long service life under demanding industrial conditions.
From the continuous caster to the coke ovens, steel and metal plants put rotating unions through extreme temperatures, heavy loads, and round-the-clock operation. Every media path is specified to match.
Supply cooling water to rolls, segments, and moulds throughout the casting strand — maintaining consistent heat extraction as the machine runs around the clock.
Transfer hydraulic oil, air, and cooling water across the rotating turret to control furnace and ladle positioning with precision under high thermal load.
Deliver cooling water and hydraulic oil to work rolls and backup rolls, holding rolling tolerances steady across both hot strip and cold reduction stands.
Handle continuous coolant and water flow to high-speed roll stands, supporting sustained throughput on long-product rolling lines.
Manage cooling water and gas transfer on rotating equipment exposed to extreme heat — built to hold seal integrity through continuous thermal cycling.
The CARBON series below are specified most often for steel and metal processing applications. Final selection should be confirmed against your operating pressure, temperature, and RPM.
