Product Description

                                             
    Spiral Blades /Straight Blades Solid Casing Centralizers

The Rigid Centralize consists of rigid body, on which machined five spiral blades or straight blades. There are three modified alloy steel, fully heat treated rollers fixed on every blade. Because of rolling friction between the rollers and inside of well or casing, the functions of the RCR Centralizer is better than others of all. Recommend to use the tool in deviated holes and horizontal holes.
  And we provide various non-welded Rigid Centralizer, which are designed and manufactured as per API Spec 10D. 
 The popular styles available are non-welded Rigid Centralizer, and double-bow spring centralizer with high reliable quality, which can be used to replace Weatherford centralizer.

 




Straight Blade Solid Centralizer provide the right features for getting a good primary cementing job with maximum casing / wellbore stand off. The straight fines / vanes do not impart hydraulic forces on pressure sensitive formations. Since there is no radial flow path for the fluids to follow, therefore solids and cuttings transport relies solely on the turbulent or laminar flow rather than radial flow.

It provides ultimate drag and torque reduction with maximum fluid by pass with low friction factor. These Centralizers are designed to minimize unwanted removal of well cake and for easy running of casing. These Centalizer withstand high well bore temperature while providing maximum horizontal stand off. These Centralizers are Well head friendly and have high impact with shock resistance, along with optimum tensile and yield strength.


straight Solid Centralizer are constructed of one-piece high strength corrosion resistance Alloy Aluminum, Alloy Steel, Stainless Steel or Non sparkling Alloy Zinc. Centralizers are available in short length, long length and standard length. Further, they can supply in fixed design and non-fixed design. These centralizer are High graded castings followed with surface finishing on CNC Lathe, then rigid inspection make a quality product. All Centralizers are stove painted or coated with polyester powder.

They are available in all sizes ranging from 3 ½" to 13 3/8" for any hole combination.
