Product Description

Spiral Blade Solid Body Rigid Aluminum Casing Centralizer


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 reset force of double bow type centralizer is higher than that of single bow centralizer, centering centering performance is better than that of single bow type.
 
features:
 
1,every attachment is pressed into shape by moulding instead of welding and rivet. 
2,3-section structure for easy transport.
3,starting force and restoring force conform to api standards.
4,easy-and-convenient to use.
5,alternative turbulence plates can effectively improve displacement efficiency.









 
cast aluminum centralizer:
 
the smooth spiral 360 overlap solid vane design of centralizers provide max wall contact will not damage wellhead equipment, has high impact and shock resistance comand 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 bine with high tensile and yield strengths
