PTFE lined Rubber Joint

    

PTFE lined Rubber Joint

Non-metallic expansion 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.

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

Features:

* 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.

Benefits:

* Lower systems design costs
* Low material costs
* No gaskets required
* Lower replacement costs

Rubber expansion joints also effectively confront these problems:

* Vibration
* Noise
* Shock
* Corrosion
* Electrolysis
* Induced Forces

Warning:
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.
