Product Description

EPDM rubber joint for drinking Water with stainless steel flanges

 

Rubber expansion joints are flexible connectors for the construction of pipe systems. They relieve system strain by reducing vibration and
noise and compensate static or dynamic movements caused by thermal change, load stress, pumping surges or construction settlement.
They also compensate assembling inaccuracies (misalignment during installation) and can be used as pipe insert pieces to facilitate inspections

Rubber expansion joints isolate or reduce vibration caused by equipment. The transmission of vibration is reduced and
they protect equipment from these adverse effects.

 

Rubber expansion joint with high quality EPDM is suitable for Drinking water, has an WRAS approval. Except this it is resistant to cold and warm waste water, seawater, cooling water, water with chemical additives, low concentrated acids and alkalis, salt solutions, technical alcohols, esters and ketones. It can handle hot water and cooling water with salt solutions as well.

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
