Non-Welded Hinged Bow Spring Centralizer for Cementing Well
This results in a highly uniform thickness between the casing and the wellbore. These centralizers are able to minimise gas channeling by reducing the movement of the pipe before the cement sets in. Additionally, these bow spring centralizers provide a semi-rigid casing standoff.
