4. The single piece centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells.

5. The single piece centralizer reduces the effect of channelling by improving the cement flow,the results in more uniform cement thickness in the well bore.

6. By reducing the pipe movement before cement sets in.The single piece centralizers are able to minimize gas channelling.

7. The single piece centralizers are one piece construction in special high strength steel which imparts excellent hardness and spring action ensuring an unmatched ability to come back to its original shape after undergoing rigorous stress loads conditions.

8. The single piece casing centralizers are available in size 4-1/2" to 20".

9. Any special sizes or combination can be available on requirment.
