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.
API 10 D casing rigid roller centralizer for sale
Top wire casing rigid roller centralizer are an integral part of the cementing process. They provide the
mechanism that centers the casing in the hole and allows uniform
cement flow around the casing to help protect it at all points.
Several styles of centralizers are available for matching different
well specifications and hole sizes, including turbulence generating
designs that help clean the annulus and distribute the cement more
evenly and uniformly. All models offer ample clearance for fluid
passage and are extra effective in centering the casing, even in
highly deviated holes and improve cement flow by reducing the
effects of channeling.
The top wire casing rigid roller centralizer consists of a rigid
body, on which machined five spiral blades. There are three or four
modified alloy steel, fully heat treated rollers fixed on every
spiral blades. The assembly is shown as following fig. Because of
rigid body and rolling friction between the rollers and inside of
well or casing, the capability of the top wire casing rigid roller
centralizer is better than others of all. Recommend to use the tool
in deviated holes and horizontal holes.
