Oilfield Aluminum Alloys Casing Centralizer
The fins or blades overlap the entire 360-degree open hole circumference and the reduced flow area between the spirals provides and creates a vortex motion that increases fluid velocity. Even without rotation, the angled fins still induce turbulent flow for improved cutting and filter cake removal. All Centralizers are stove painted or coated with polyester powder.
