Product Description

                                    API one-piece integral 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.
Bow-spring centralizer
1.These centralizers are designed for high restoring force and low starting force for centralizing the casing pipe in a vertical, horizontal and deviated well
2.Premium quality bows are made of special alloy steel and hot formed in totally controlled heat treatment plant to achieve the uniform hardness all over

3.Spec and performance index of bow spring casing centralizer meet api spec 10d.The woven centralizer is connected by pin when in use, the unfolded centralizer can be stacked flatly for convenient storage and transportation.
Rigid roller centralizer
Rigid casing centralizer is used in deviated wells and horizontal wells.There are several blades on the rigid roller centralizerthat can keep casing from contacting the wellbore wall
