Well Cementing Solid Stemped Spiral Vane Centralizer High Anti-Impact
There are three processed methods of solid rigid centralizer,one is casting,the second is integral punching and end welded by CO2 shielded arc welding,the third is cutted by seamless pipe and the blade is processed by steel plate and then processed by lathe.
Stamped Solid Centralizer is designed to provide a positive stand off the casing(we also call it slip on stand off band).
This type centralizer provides a bearing surface for lower torque and drag forces, and undergo a special coating to prevent from rust.
The blades design can reduce minimum friction when running a casing duo to the smooth profile.
Increase flow-by area to optimize mud displacement in vertical,inclined,and horizontal wells.
Available in straight or spiral blades, these blades are mechanically formed rather than welded onto the centralizer body.
The set screws can be integral with solid rigid centralizer body and then help save operation time and cost.
