Features and Benefits:

Absorbs Directional Movement

Thermal movements appear in any rigid pipe system due to temperature changes. The Liwei brand wide arch expansion 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.)

Less Turbulence or Material Entrapment

The LIWEI Brand expansion joints are manufactured with the integral rubber flange joining the body at a true 90º angle. This ensures the product will install snug against the mating pipe flange free of voids creating less turbulence in the pipe system. The LIWEI brand is also available with a filled arch for applications that have 20% or more solids in the process.

Absorbs Vibration, Noise and Shock

The Liwei brand rubber expansion joints 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 LIWEI brand  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. Install the LIWEI brand rubber joints 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.)

Wide Service Range and Less Weight

Engineered to operate up to 200 PSIG (nominal size dependent) Or up to 250ºF (elastomer dependent), the Liwei BRAND can be specified for a wide range of piping system requirements. The LIWEI brand  rubber expansion joints are constructed in various elastomers with rubber impregnated polyester tire cord and reinforced with wire to create a product with greater operating performance.
