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.
