Product Description

Composite Casing Centralizer
 

Features of Composite Centralizers:

Material: thermoplastic Polymer. It have lower friction coefficient than steel centralizers, only have 50%.

Composite centralizers withstands high well bore temperature up to 200 degree.   

Reducing the drag force, flow area, increase maximum centralization and with high standoff.

Usage: well drilling

Size: 4 1/2" to 20" available. We accept custom size.

Advantage of Composite Centralizers

1. Composite nylon rigid centralizers is designed to reduce drag and friction down hole it have lower friction factors, ultimate drag and rotational torque reduction, increased abrasion resistance for maximum stand-off. 
2. Vanes are designed to enhance hole cleaning using maximized flow-by area. 
3. They are design to provide optimum flow and its fins or blades overlap the entire 360-degree open hole circumference.
4. Therefore it reduces flow area between the spiral vane and creates vortex motion to increase fluid velocity with direction. 
5. Extra length of fins gives maximum centralization, high stand off and increase annular turbulence. 
6. Even without rotation, the relived angle fins/ blades induce turbulent flow for improved cutting and filter cake removal. 
7. Composite nylon rigid centralizers withstands high well bore temperature up to 200 degree Celsius while providing maximum horizontal stand off. 
8. Composite nylon rigid centralizers are well head friendly and have high impact with shock resistance, and Shock proof along with optimum tensile and yield strength. 
9. Composite nylon rigid centralizers are constructed of one-piece in superior quality polymer. 
10. Composite nylon rigid centralizers are available in standard length only. The composite nylon rigid centralizers has surface finishing on CNC Lathe, and then rigid inspection makes a quality product. 
11. Composite nylon rigid centralizers are available in all sizes ranging from 4 1/2" to 20" for any hole combination.
12. Any special sizes are available on request.
