Product Description

eccentric rubber expansion joint is a single open wide arch type. Eccentric in design, the expansion joint body tapers on one side transitioning two different flange sizes.

Features and Benefits:
Absorbs Directional Movement
Thermal movements appear in any rigid pipe system due to temperature changes. wide arch joints allow for axial compression or axial extension, lateral deflection as well as angular and torsional movements. (Note: Rated movements in this publication are based on one plane movements. Multiple movement conditions are based on a multiple movement calculation. Contact YU-xiang for information when designing multiple pipe movements.)

Less Turbulence or Material Entrapment
eccentric rubber expansion joint are manufactured with the integral rubber flange joining the body at a true 90° angle. This ensures the product will install snug against the mating pipe flange free of voids creating less turbulence in the pipe system. For applications where 20% or more solids are present, use the filled arch eccentric rubber expansion joint for smooth bore transition with no possibility for material entrapment.

Absorbs Vibration, Noise and Shock
eccentric rubber expansion joint effectively dampen and insulate downstream piping against the transmission of noise and vibration generated by mechanical equipment. Noise and vibrations caused by equipment can cause stress in pipe, pipe guides, anchors and other equipment downstream. The expansion joints will help relieve noise and vibration occurrences in a pipe system. Water hammer and pumping impulses can also cause strain, stress or shock to a piping system. to help compensate for these system pressure spikes.

Compensates for Misalignment
Rubber expansion joints are commonly used by contractors and plant personnel to allow for slight pipe misalignment during installation of new piping and or replacement applications. (Although rubber expansion joints can be made with permanent offsets, it is suggested that piping misalignments be limited to no more than 1/2 the rated catalog movement. Contact Yu-xiang for resultant movement capability.)

Wide Service Range and Less Weight
Engineered to operate up to 200 PSIG (nominal size dependent) or up to 250°F (elastomer dependent), the eccentric rubber expansion joint  can be specified for a wide range of piping system requirements. The eccentric rubber expansion joint are constructed in various elastomers with rubber impregnated polyester tire cord and ASTM wire to make up the pressure restraining member. This lightweight design installs easily and costs less to ship.

Material Identification
dates and elastomer designations. All Neoprene Tube/Neoprene Cover (NN) and Nitrile Tube/Neoprene Cover (NP)elastomer designated joints meet the Coast Guard Requirements and conform to ASTM F 1123-87.
