Product Description

casing bow spring centralizer

Super-strength spring steel is applied to centralize casing in wellbore,and improve cementing quality.

Features:
1,Every attachment is pressed into shape by moulding instead of welding and rivet.
2,3-section structure for easy transport.
3,Starting force and restoring force conform to API standards.
4,Easy-and-convenient to use.
5,Alternative turbulence plates can effectively improve displacement efficiency.

API 10d Single Piece Centralizer, Slip on Casing Centralizer

1) Material: 65Mn steel

2) Type: Single Piece

3) Standard: API 10D

4) API and ISO certified

5) Specifications: 4 1/2''---20''. More special sizes or combination are available as requested

6) Characteristic: This kind of single piece casing centralizer has restoring force almost two times of API standard.

7) Application Bow spring centralizers are to help center the casing in the wellbore, allowing even distribution of the cement around the casing during cementing operations. The single piece casing centralizer is made from special high strength steel (65Mn steel), which gives more excellent hardness and spring action than other types of centralizers.

8) Function a. Take casing to designed position by reducing sticking while casing going down. b. Centralize casing in well. c. Balance liquid pressure in annular space by reducing adhesion phenomenon. d. Improving replacing ratio of mud and boosting cementing quality by reducing channeling effect.

9) Features: a. Designed for high restoring force and low starting&running force b. Undergo special coating process to prevent from rust
