Absorbs Directional Movement
Thermal movements appear in any rigid pipe system due to temperature changes. The REJ1 and REJ2 spherical arch expansion joints allow for axial compression or axial extension, lateral deflection as well as angular movement. (Note: Rated movements in this publication are based on single plane movements. Multiple movement conditions are based on a multiple movement calculation. Contact customer service for information when designing multiple pipe movements.)
Easy Installation with Rotating Metallic Flanges
The floating metallic flanges freely rotate on the bellows, compensating for mating flange misalignment, thus speeding up installation time. Gaskets are not required with the REJ1 or REJ2, provided the expansion joints are mated against a flat face flange as required in the installation instructions.
Flange Materials/Drilling
The REJ1 and REJ2 molded expansion joints are furnished complete with plated carbon steel flanges for corrosion protection. 304 or 316 stainless steel flanges are available upon request as well as ANSI 250/300 lb., BS-10, DIN PN10 & PN16 and JIS-10K drilling.
Absorbs Vibration, Noise and Shock
The REJ1 and REJ2 molded expansion joints effectively dampen and insulate downstream piping against the transmission of noise and vibration generated by mechanical equipment. Noise and vibration caused by equipment can cause stress in pipe, pipe guides, anchors and other equipment downstream. Water hammer and pumping impulses can also cause strain, stress or shock to a piping system. Install the REJ1 or REJ2 molded expansion joints to help compensate for these system pressure spikes.
Wide Service Range with Low Cost
Engineered to operate up to 300 PSIG or 265°F, the REJ1 and REJ2 can be specified for a wide range of piping requirements. Compared to conventional hand-built spool type joints, you will invest less money when specifying the mass-produced, consistent high quality, molded single or twin sphere expansion joints.
Features and Benefits:
Flexible Solutions For Today's Rigid Industries
The molded REJ1 single sphere and REJ2 twin sphere designed bellows are inherently stronger than the conventional hand-built style spool arch type. Internal pressure within a “sphere” is exerted in all directions, distributing forces evenly over a larger area. The spherical design “flowing arch” reduces turbulence and sediment buildup.
