Common Applications of Rubber Flexible Joints

In Heating, Ventilation and also Air Conditioning (HVAC) systems rubber flexible joints play an important function in keeping effectiveness as well as convenience. These systems usually experience resonances from followers, compressors and also pumps. Without appropriate resonance seclusion these resonances can result in sound contamination endure or perhaps system damages.

Example: In a big office complex rubber flexible joints were mounted to attach a/c systems to ductwork. These joints dramatically decreased functional sound and also taken in thermal development in the air ducts, boosting the system’s total reliability.

Water and Wastewater Systems

Rubber flexible joints are extensively utilized in water therapy plants along with sewer systems. They fit stress rises avoid pipeline misalignment along with take care of thermal development in pipes lugging water or sewer.

System Types:

  • Drinkable Water Systems: Their safe and secure rubber products guarantee secure transport of alcohol consumption water

  • Waste Water Therapy Plants: These joints stand up to the rough and also destructive nature of wastewater, lengthening pipe life
