Flexible rubber joints have been used in place of the traditional all-metal expansion joints to solve problems caused by the thermal and mechanical stresses generated in complex systems. Even though the power generation industry is a main user of rubber expansion joints, the product has found acceptance in many other industries.
1:Three reasons to use rubber expansion joints:
1. To prevent stresses due to expansion and contraction 2. To insulate against the transfer of noise 3. To compensate for misalignment
Large movement potential: the non-metallic expansion joint offers multi-plane movements in a shorter face-to-face dimension.
Corrosion resistance: the ability of various rubbers and plastics to stand up to corrosive chemicals can extend the life of an expansion joint.
Sound and vibration elimination: the outstanding vibration and sound attenuation characteristics of elastomers help prevent premature system degradation.
Ability to stand up to high temperatures: with the use of special materials, non-metallic expansion joints can withstand over 1000°F operating temperatures.
Lower systems design costs
Low material costs
No gaskets required
Lower replacement costs
Rubber expansion joints also effectively confront these problems:
Inner rubber lining
Outer rubber lining
Polyester cord frbrica
Expansion joints may operate in pipelines or equipment carrying fluids and/or gases at elevated temperatures and pressures. Precaution should be taken to insure proper installation and regular inspection. Care is required to protect personnel in the event of leakage or splash.
