The Centralizer Sub offers a unique solution for centralizing and cementing casing/liner strings from 5” to 18”. Our proprietary design allows for the bows to sit flush against the shell with full-rotating capability, providing optimum performance in tight-tolerance and/or underreamed hole conditions.

  • Rounded bows compress flush with the body of the centralizer to pass smoothly through tight restrictions, won’t damage wellhead seals
  • Proprietary end bands “pull” the centralizer into or out of the wellbore
  • Grease ports allow smooth rotation of the centralizer; prevents corrosion between body and end bands
  • Standoff meets or exceeds API Specification 10D requirements
  • Body meets or exceed burst and collapse ratings of host casing
  • Body maintains ID drift diameter requirements of the casing in which they are run and OD drift requirements of all previous casing strings
  • Rotating design on all models and sizes
