Stamped Spiral 7″×8-1/2″ Bow Spring Centralizer
Stamped Spiral Centralizer
Stamped Spiral centralizer enables optimal mud displacement for vertical, deviated, and horizontal wells. Special rounded blades reduce casing-sliding friction compare with the square blades and are suitable for reciprocation and rotation during cementing.
-
Stamped Spiral Centralizer is to provide a positive stand off the casing
-
For lower torque and drag forces, and undergo a special coating to prevent from rust.
-
Increase flow-by area to optimize mud displacement in vertical,inclined,and horizontal wells.
-
The blades design can reduce minimum friction when running a casing duo to the smooth profile.
-
The set screws can be integral with solid rigid centralizer body and then help save operation time and cost.
-
Available in straight or spiral blades, these blades are mechanically formed rather than welded onto the centralizer body.
