API 10D Slip on Bow Spring One Piece Centralizer
Character:
1. It's finished well under mould pressing without any welding.
2. Starting and restoring force meets API 10D standards.
3. Easy and convenient to install.
4. Equipped with spinning disc to improve the displacement efficient.
Product Advantage:
1. API single piece casing centralizer performs satisfactorily in open hole as well as cased hole.
2. These high quanlity product,developed to meet and exceed API 10D specifications for use in highly demanding downhole conditions.
3. Single piece casing centralizer combines the highest restoring force with zero start force and zero running force.
4. The bow spring casing centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells.
5. The single piece centralizers reduce 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 casing 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".
