Aluminum Cementing Plugs

Aluminum Cementing Plugs

Industrial Rubber Aluminum Cementing Plugs are engineered for strength and dependability in large casing diameters. Three self-centering cups with wiping elements bolted to an all-aluminum core.  The one-piece cup and wiper elements are made of 70 durometer natural rubber.

 
 
 

 

  • Three self-centering cups with wiping elements bolted to an all-aluminum core. 
  • PDC drillable.
  • Differential pressure across the plug forces both wipers and cups firmly against the casing wall to create firm wiping action throughout the length of the casing string.
  • The all-aluminum core resists distortion from pressure in a deep well and gives support to long columns of either cement slurry or drilling fluid. 
    The bottom cup design provides a positive shut-off when it seats on the landing joint. 
  • These plugs permit the use of conventional cementing methods in 16” through 20” casing sizes.
