DN150-230mm EPDM Rubber Expansion Joint

EPDM Rubber Expansion Joint
Fustar EPDM rubber expansion joint are designed to reduce vibration and dampen sound transmission.They are also designed to take the movements such as : compression movements ,extension movements,angular movements,torsional and lateral movements.Our main rubber materials are:EPDM,Neoprene,Nitrile, Hypalon,Viton and Natural rubber.

Features of EPDM Rubber Expansion Joint
• Reduce Vibrations
• Dampen sound transmission
• Compensate lateral,axial,torsional and angular movements

• Light weight

• Low movement forces

• Reduce fatigue factor

• Reduce heat loss

• Corrosion,erosion resistant

• Acoustical impedance 

• Greater shock resistance

 
Function 
Fustar designed rubber expansion joints are flexible,reinforced elastomers which are used in piping systems to meet the following major needs:

• To protect piping by absorbing any difference in dimension due to temperature variation or line movement.

• To protect equipment such as supports & anchors,pumps,valves,turbines,condensors & other line equipment by reducing equipment vibration.
• To provide simple connection of misaligned pipes.
• To improve man's comfort by limiting noise from fluid circuits.
• Elimination of Noise and Vibration: Two characteristics combine to reduce vibrations transmitted by the pipe well and by the fluid itself.

   a , A break in the pipe material,i.e. no metal-to metal contact;

   b , A damping effect provided by the convolution in the joint.

• Movement Accomodation.
