Product Description
PTFE Joint Expansion Rubber With Food Grade DN50-DN800
Our PTFE expansion joints are made from the synthetic material Polytetrafluoroethylene, the non reactive material is widely used in pipelines
within the chemical manufacturing industry, acting as a protective agent against corrosive substances.
PTFE Polytetrafluoroethylene also has less surface friction than rubber, which means that flow can be improved by using PTFE hoses.
While rubber is prone to break down at extreme temperatures, PTFE is highly temperature resistant, making it ideal for all kinds of industries.
The PTFE liner serves as a primary skin to the fluid being transferred while the body of the rubber or metal expansion joint serve as a
secondary measure to prevent leakage from the joint. The PTFE also gives metal joints added protection against corrosion by keeping
the liquid away from the metal convolutions.

FEATURES
Absorb Axial movements (extension and compression).
Axial movement is the change in dimensional length of the bellows from its free length in a
direction parallel to its longitudinal axis.
Absorb Lateral movements.
Lateral movement is the relative displacement of one end of the bellows to the other end in a direction perpendicular to its longitudinal axis.
Absorb Angular and Torsional Movements.
Angular movement is the rotational displacement of the longitudinal axis of the bellows toward a point of rotation. Torsion refers to twisting one
end of the bellows with respect to the other end, about the bellows centerline.
Reduce Vibration.
Rubber expansion joints isolate or reduce vibration caused by equipment. The transmission
of vibration is reduced and they protect equipment from these adverse effects
Dampen Sound Transmission.
Rubber expansion joints tend to dampen transmission of sound because of the steel rubber interface of joints and mating flanges.
Manual and Install Notes of the Rubber Joint
1, The installation of expansion joints shall be in accordance with the expansion of piping construction drawings and installation instructions requested
2, Install expansion joint of the pipeline must be approx. to increase fixed by the orientation
and expansion joints can be made to play a role, so orientation and fixation of the settings must be in strict accordance with the design departments of the technical information. For orientation, the principle of setting a fixed support, please see "Bellows Expansion joints Installation Guide."
3, With a bellows expansion joint is formed with a thin stainless steel plate, so lost in moving, hoisting and welding should be careful not to hit the period, scratch, arc,weld spatter and other reasons to bellows damage
4, Should be removed before installation and piping bellows foreign body to ensure normal movement bellows
5, On a flow of media requests for expansion joint should be required to install the flow arrows
6, In order to make bellows in good working condition,can not install expansion joints in the deformation, including axial, lateral, turn transfer pipe installation error
7, Expansion joints installed, running in the system before moving to remove all painted yellow lose a fixed screw
8, Fabric fiber expansion joint is not subject to the tensile displacement due to the installation to the proper conduct of the pre-compression, the pipeline can not deflection, displacement and axial extension, should be noted that flexible ring of protection against scratches, installed as soon as possible to dismantle support board, so that in normal working condition
