A mechanical device that keeps casing from contacting the wellbore wall. A continuous 360-degree annular space around casing allows cement to completely seal the casing to the borehole wall.
1.Description:
These Centralizers are designed for High Restoring Force and Low Starting Force for centralizing the casing pipe in a Vertical, Horizontal and Deviated well. 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.
1). Starting and restoring force meets API 10D standards
2). Removable and easy to use and transportation
2.Characteristics:
1) Model processing, no rivet, no welding
2) Easy for installation
3) Low starting and running force, substantial restoring force
4) Conform to API 10 D
5) Modle:Self (double)-bow centralizer
6) Competitive price with high quality
