Well Completions Solutions

Single piece, solid steel casing centralizers

Made from high-quality spring steel and subjected to special thermal treatment to achieve minimal starting force while maximizing spring strength
Resistant to high axial and radial loads
Free of welded joints and constructed from a single sheet of steel, including the centralizer’s collars
Provides the necessary eccentricity for effective cementing
Centralizer blades are rolled and conform to the cylindrical shape of the wellbore
Minimizes the risk of casing sticking
