• Rubberexpansionjoint

• 

• USES: mainly used for the inlet and outlet of pipeline system and pump parts, used to absorb the noise on the line and vibration and due to temperature changes or vibration caused by foundation settlement and the vibration of the pump pipe elongation, shrinkage, or eccentric axis direction and horizontal direction of displacement of the mobile and angle change.
  Construction features：
  Appropriate soft structure can absorb the external force caused by deformation, and can recover quickly.
  The root of the flange with a certain length of intubation into rubber layer, can avoid the root of the flange rubber place to produce stress concentration caused by the damaged, anti-bending of effectively extend the product life of deformation (type A and type B).
  

  

  
  High arch span structurecan adapt to the positive and negative variations without damage.
  Light weight, small flange length, the small space.
  Don't need another gasket, baffle,it can be installed directly by bolt.
  Type：
  Type A: Resistance to high pressure, high consumption situations.
  Type B: General use of the soft structure.
  Note: Structure can be designed into one end of the lap joint flange.
  Such as expansion joint installed at both ends or one end cannot reallyfixed, unable to avoid the damage of expansion joint or pipeline which caused by the thrust of internal pressure, the expansion joint must be designed to the limit ear plate structure. Fluid in the sediment will stay in the mountain of the concave area, if you have any worry about the not easy moving of sediment, the entity mountain type expansion joint can be used in such case. (This expansion joint is on the original empty body cove department to join the soft rubber material and the overall expansion joint is an organic whole to sulfide, in order to ensure that the inner surface is smooth). But, the allowance of deformation of this kind expansion joint is onlyhalf of the normal produce.Such as displacement cannot meet the requirements, the number of mountain should be increased accordingly.
  

  

  
  Expansion joint data table：
  
  Note: Allow the displacement in the table according to standard 1 mountain said.
  Please inform us in advance about the following items:
  The length of the inside diameter and necessary flange standard specifications
  Fluid type, concentration, maximum servicetemperature and pressure
  Whether install the limit device or not.
  The environment of usage occasion (temperature).
