ELSX ROTARY JOINT The ELSX rotary joint is the next generation of extended life, self-supported (ELS) rotary joints for use in steam and thermal oil applications. It is designed to perform under high-pressure, high-speed, and high-vibration conditions. Its convex seal design delivers up to 20% more combined pressure and velocity (PV) capability and up to 15% more seal ring wear life than an equivalent ELS rotary joint in steam applications. Its increased carbon guide separation and contact surfaces ensure greater horizontal pipe stability and longer life. The ELSX rotary joint enables faster runnability and increased up-time. Sizes are available in 2′, 2.5′,3′, and 3.5′. The rotary joint is rated up to 500° F (260° C), 300 psig (20 bar), and 300 rpm for steam. It is rated up to 650° F (343° C), 150 psig (20 bar), and 300 rpm for thermal oil. FEATURES Robust convex seal design Designed for steam and thermal oil Wide carbon support guide separation and wear surface Standard O-ring or preformed packing BENEFITS Faster run rates High combined pressure and velocity capability Extended carbon guide and seal ring wear life Application and installation flexibility Easy to maintain, no special tools required
