These rigid centralizers are used where casing centralization is the main consideration, such as to centralize large casing strings to facilitate the cutting of casing during well abandonment.

This kinds of solid rigid centralizers are available with or without setscrews which are used to tighten the casing.The length is available in short as well as long.

Not only the straight blades solid rigid centralizer has function of self-cleaning going into wellbore,but also it is with less restriction of flow than other casing centralizers. Designed for use in highly deviated and horizontal wells and act as bearing during pipe rotations.
