5. Introduction

These centralizers are specially manufactured for extra load highly deviated or horizontal wells and for use with Liner Hangers.

Steel construction provides superior toughness over other materials. The boat-shaped Spiral fins reduce Drag Forces during running pipe. The fins glide smoothly in the low side of parallel boreholes.

Wide symmetrical fins are smoothly beveled on one and the other ends to have lower coefficient of friction and to ease casing movement in either direction. Fins designs also resist high side load.
Spirally Fins are welded to the one piece rolled formed End Collar under required temperature and condition with extra low Hydrogen coated Electrodes, which assure strength and uniformity in every weld. Steel construction provides superior toughness over other alloy.
Vanes can be selected to meet any hole dia from a alternative of seven boat profile depths. They are provided for direct installation on the pipe by slipping on and can be provided with suitable Stop Collars beveled from one side positioned by set screw.These centralizers undergo a special coating process to restrict from Rust then coated with special Polyester Powder.

Design appearance-one solid piece design; features straight steel bars welded to solid 5-in. tall body.Performance-provides positive casing standoff.ApplicationsUsed in most types of well designs.Most suited for horizontal and directional well designs; favorable in cased hole situations.Recommended to run between two 212-series stop collars or one stop collar and casing coupling.Recommend running all rigids between stop collars to allow centralizer to function as a bearing and to reduce torque.6.
