Solid rigid centralizers are one series of casing centralizers, which are integral part of cementing processing. They are built out of solid steel bar or cast iron with a fixed blade height and are sized to fit a specific casing or hole size. It is available in steel or aluminum materials with spiral or straight blade body construction in standard and customized sizes to match different casing sizes and wellbore conditions. Roller centralizers are also available for customers' requirements. Solid rigid centralizers are available in deviated or horizontal wells. But it is rarely selected in the vertical wells because of the smaller diameter than the wellbore.

  • Fully heat treated rollers are fixed on every straight or spiral blades/vanes.

  • Better capacity than the straight/spiral vanes solid centralizers because of rigid body and rolling friction between the roller and inside of well or casing.

  • Made of cast steel, which is high tensile and solid for shock and impact resistance

  • Roller/wheeled centralizers are mainly used for high deviated wells and horizontal wells to centralize casing.

  • Can remove wellbore cake and improve mud replacement efficiency.
