Api standard ridgid spring casing centralizer/Integral stamping
ridgid spring centralizer
1.Description:
Solid body casing centralizer is developed specially for horizontal
and extended reach wells with Up to 50% lower coefficient of
friction over steel centralizers. It enables casing strings to
reach total depth efficiently while providing good standoff for
optimal mud displacement and greatly enhancing cementing
operations.
