Product details

Description 
A metal strip shaped like a hunting bow and attached to a tool or to the outside of casing. Bow-spring centralizers are used to keep casing in the center of a wellbore or casing ("centralized") prior to and during a cement job.

A device fitted with a hinged collar and bowsprings to keep the casing orliner in the center of the wellbore to help ensure efficient placement of acement sheath around the casing string. If casing strings are cemented off-center, there is a high risk that a channel of drilling fluid or contaminated cement will be left where the casing contacts the formation, creating an imperfect seal.
