EPDM NBR Two Ball Twin Sphere Rubber Expansion Joint With Galvanized Flange

EPDM NBR TWO BALL TWIN SPHERE RUBBER JOINT WITH GALVANIZED FLANGE

Flexible rubber joint, abbreviated as rubber joint, is a joint made up of fabric reinforced rubber parts and flat movable joints,

metal flanges or threaded pipe flanges, used for pipeline vibration isolation, noise reduction, and displacement compensation.

It is a pipeline joint with high elasticity, high airtightness, medium resistance, and weather resistance.

Double Sphere Rubber joint with two corrugations from outside, fitted flanges are with cold zinc /galvanzied surface.
The flanges fitted can be with material carbon steel, galvanized and stainless steel.

Twin Sphere Rubber expansion Joint

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.
