Product Description

 API Non Welded Rigid Centralizer, Positive Casing Centralizer

Zhongshi Non Welded Positive Centralizers are uniquely designed with flat bottom U profile of different depths. The Centralizers significantly reduce frictional drag while being used in deviated holes. They provide almost 100% Stand Off when run inside a cased hole. They are supplied ¼" or 6 mm less than the inside diameter of the hole size in which Centralizer is to be run. This design eliminates weak (brittle) spots passage. U profile bow design permits maximum fluid passage.
End Collars are designed with self-locking action, which are easy to assemble, time saver and strong grip. The Ten special U sizes Bows can configure to any hole diameter. These Bows with extended profile prevent them from hitting against casing collars. Bows are of high quality steel for consistent characteristics.
They are available in 4 ½" to 20 " sizes. Any special sizes or combination can available on request.
