4 Inch Single Sphere Rubber Expansion Joint Customizable Vibration Reduced Non Electrolysis

Expansion joints for piping systems are flexible connectors, made out of PTFE, natural or synthetic elastomers, with combinations of rubber, fabric and metal reinforcement. Expansion joints installed into piping systems will help solve problems such as:

• Stresses - expansion joints absorb movement due to thermal expansion and contraction of pipes, wear, load stresses and settling of supports and foundations
• Misalignment - custom expansion joints can be manufactured with offsets to account for installation errors in pipe alignment, or for movement and settling over time
• Abrasion - with proprietary elastomers such as ABRA-LINE, abrasion can be significantly reduced compared to other rubber or metallic connectors
• Vibration - rubber expansion joints significantly reduce vibration when installed in proper locations and are not subject to metal fatigue failure
• Noise - transmission of sound is reduced as the expansion joint acts as a dampener and absorbs the noise levels
• Shock - effects of pressure surges, water hammer, or pump cavitation are resisted
• Corrosion - no metal to metal contact eliminating electrolysis between dissimilar metals
• Space - greatly reduced space required compared to expansion bends or loops

To select the proper piping expansion joint, it is critical to understand the media compatibility with the materials selected, full temperature, pressure and vacuum ranges, movements required, and dimensions between pipe flanges. With this information, JINGNING application engineers can assist in determining the ideal expansion joint for any application.
