4 1/2''---20'' Single Piece Centralizer With Excellent Hardness 65Mn Steel

4 1/2''---20'' Single Piece Centralizer With Excellent Hardness 65Mn Steel

Single Piece Centralizer Introduction

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

Single Piece Centralizer 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.

. Produced and tested to meet API 10D specification .

. Robust single piece design, suitable for onshore installation

. Tiny starting forces and restoring forces are much great than API standard .

. Flexible design reduces running forces through any cased hole restrictions, has an extremely low co-efficient of friction, speed the process of running casing liners to final depth.
