Low-Friction Composite Turbulizer-Centralizer
A one-piece, non-removable cast structure made of composite material.
Advantages
- one-piece, non-removable cast construction;
- secured by stop rings and set screws;
- allows rotation of the casing string;
- rounded blade profile with right-hand orientation.
Specifications
- dry friction coefficient: as low as 0.1
- holding force of the screws: 6 tf
- number of blades: 4
- longitudinal / transverse compressive strength: from 22.2 t
- size range: 114/146; 140/207; 146/214; 178/214
Application area and experience
The low-friction composite turbulizer-centralizer is designed to reduce the friction coefficient when running the casing string into the well, to reduce the eccentricity of the string’s position in the well, and to create a turbulent fluid flow during cementing.
