Non-weled Hinged Rigid Crest Casing Centralizers
Casing centralizer as a cementing tool is applied in vertical, deviated and horizontal wells to centralize casing for improving the cementing quality. The cement could be concreted firmed between casing and borehole wall.Our centralizer with API standard sizes range from 4-1/2” to 26” and surface is coated by powder baking or paint baking. The products have high tensile and yield strength, shock, impact and corrosion resistance performance.
Non-weled Hinged Rigid Crest Casing Centralizers Features - Under reamed and washed-out wells.
- The high-quality, spring-steel bows are heat treated to optimize standoff in gauge holes
- Various bow shapes and heights are available to provide optimum restoring forces for most well requirements.
