Product Description

API Rotating Centralizer, Rigid Centralizer

Casing centralizer is one of the necessary conventional casing accessories, upon well operations completion, 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.

Description:
Solid Rigid Centralizers are available in Straight Blade or Spiral models and are made to run on the casing OD to centralize the casing that will be cemented in the wellbore and will also improve cement bonding onto the casing. They are designed to reduce the amount of friction between the casing and the hole, allowing the casing to be inserted more easily into the wellbore; and help prevent the casing string from becoming differentially stuck.
