Non Weld Bow Spring Centralizers
centralize the casing in bore hole, prevent differential
sticking and provide smoother running capability by
reducing frictional forces. They provide annular space
for efficient operation of the mechanical cementing
aids, increase displacement efficiency, allow casing
to be reciprocated or rotated, limit filter cake removal
during run in and provide reinforcement to cement column.
They combine the advantage of high restoring force,
low moving and starting force. Non Weld Bow Spring Centralizers
are preferred for most applications. These centralizers
are API 10D monogrammed.
