Casing centralizer is one of the necessary conventional casing accessories, upon well operationscompletion, the rational use of casing centralizer can play the role of:

     Reducing lower casing resistance phenomenon, making the casing smoothly down to the design position;

     Making casing centralizer centered within the well;

     Reducing the sticking phenomenon to make the annular space hydrostatic pressure balanced;

     Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality.

The smooth spiral 360 overlap solid vane design of centralizers provide max wall contact and fluid swirl.The 30slope from the body to the height of 

the vane will eliminate scraping,or digging into the formation.
The solid cast aluminum centralizers will not damage wellhead equipment,has high impact and shock resistance combine with high tensile and yield 

shs.
