4-1/2" To 20" Semi Rigid Centralizer For Vertical Deviated And Horizontal Wells

4-1/2" To 20" Semi Rigid Centralizer For Vertical Deviated And Horizontal Wells

Semi Rigid Centralizer introdution

1. The bow spring centralizer is made of 65Mn steel which is better tensile strength than general steel

2. This kind of single piece casing centralizer has restoring force about 198% higher than API standard.

3. The bow spring centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells.
4. The bow spring centralizer reduces the effect of channelling by improving the cement flow,the results in more uniform cement thickness in the well bore.
5. By reducing the pipe movement before cement sets in.The single piece centralizers are able to minimize gas channelling.
6. The bow spring 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.
7. The bow spring centralizers are available in size 4-1/2" to 20".
8. Any special sizes or combination can be available on requirment.
9. This centralizer undergoes a special Iron phosphate coating process to prevent it from rust and coated with special polyester powder.
 

1) Cast steel and aluminum are available 

2) Optimizing mud displace and minimizing pressure frop across centralizer 

3) Blades are made at an angle of 30 degree with curved and sloping ends to prevent the edges embedding into formation in applications when the casing is roated 

4) Easy to install
