This types of centralizer is used with drill pipe.

Features

• Non API rated
• Customized blades consist of carbon fiber ceramic material bonded directly onto customer's casing
• Blade geometry and spacing designed to fit specific well applications
• Can be installed on any grade of pipe including CRA alloys
• Patented bonding process helps assure a strong mechanical bond with high adhesion value
• Provides centralization option for close tolerance wellbores
• Provides smooth, uninterrupted fluid flow during mud circulation and cement placement due to the absence of any banded product placed around the casing;  Helps enable full-coverage cement slurry distribution Composite material exhibits extreme abrasion and impact resistance
• Ideal for deviated sections of borehole as material combined with the upset edge of the blade geometry provides a low coefficient of friction
• Field proven technology
• Blade material is inert and thus is CO2 and H2S resistant
• A high thermal degradation temperature and excellent impact resistance at -25°F (-32°C)
• Successfully used in both conventional and slim profile wells
• Blade applications are usually performed in a Halliburton facility or in a pipe yard where customer's pipe is stored. Field location installations are also available.
