Product Description

Non Welded Hinged Bow Spring (Elastic) Casing Centralizer

1. Type: Non Welded Hinged Bow Spring Centralizer

2. Introduction
Nonweld Bow Spring centralizers centralize casing or tubing in the wellbore during running and cementing operations. The high-quality, spring-steel bows are attached to integrated, hinged end collars with locking tabs.
The hinged design enables the end collars to be latched onto casing over a stop collar, if desired, for easy installation. The centralizer should preferably be fitted over a stop collar to facilitate pulling the tool in and out of the wellbore. The nonweld design provides reliable downhole performance in cased-hole or
openhole applications. The bows provide maximum standoff to achieve efficient displacement of mud and cement.
Nonweld Bow Spring centralizers are available in several bow heights and sizes to ensure optimum restoring force and provide in a variety of bow configurations for special applications.

3. Application
 Tubing or casing applications
 Vertical and deviated wells
 Wells where rotation capabilities are not required
 Cased and open holes
