PTFE Lined Rubber Joint

Product Description

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.

PTFE lined stailess steel expansion joints 

FEATURES

• High density for low permeability.
• High tensile strength for greater working pressures.
• Low crystallinity for longer flex life.
• Material orientation for reduced stress concentrations and / or premature fatigue failure.

Note: Nom-Length is approximate and may vary.
Each PTFE expansion joint comes with metal flanges and tapped bolt holes that accommodate bolts in accordance with ANSI B16.5. Additional tapped holes are available for connecting Corning Style 11 flanges,
