Specification of Positive Casing Centralizers :
These Centralizers are
provided with rigid bows of U-profile design instead of
sprig bows to ensure maximum fluid passage. These are also
non-weld and rugged in construction. The positive
centralizers are used where casing inside a cased well is
lowered. It keeps the casing centered in the cased we’
enables proper positioning of packer and other installations
in the casing and facilitates stage and surface cementing.
It also protects previously run cemented casing from shocks
and vibrations caused by drilling.
