Product Description

Composite Centralizer

Features of roller thermoplastic centralizer: 
1. Material: Nylon thermoplastic polymer. It have lower friction coefficient than steel centralizers, only have 50%. And have resistance to high temperature. 
2. Nylon thermoplastic polymer centralizers withstands high well bore temperature up to 200 degree. 
3. Spiral vane design reduce the drag force, providing optimum flow area, increase maximum centralization and with high standoff. 
4. The roller makes it to be the sliding friction instead of rolling friction when the casing is down, thus greatly reduce the friction between the casing and the borehole wall. 
5. Usage: Well drilling
6. Size: 4 1/2" to 20" available. We accept custom size.
