Non-weld Rigid Positive Casing Centralizer


Positive bow centralizer is used for both casing and tubing applications that require concentric casing strings.

In deviated cased holes, the centralizer significantly reduces frictional drag and can provide nearly 100% standoff.

Non-weld Rigid Positive Casing Centralizer Features
  • It requires concentric casing strings and used in deviated well and horizontal well.
  • The design can reduce the frictional drag when used in casing running.
  • According to fluid density and quantity in the well , the height and depth of the U profile can be designed as required.
  • The featured U-profile design is easy to keep the fluid flow at nearly 100% stand off,generally speaking,it is at 67% stand off,so it is more effective than conventional bow spring centralizer.
