Product Description

Bow Spring Centralizers

 

Bow spring centralizers have slightly larger diameter than the wellbore, which is effective in vertical and slightly deviated wellbores to centralize the casing in borehole so as to improve the cementing efficiency.

Bow spring centralizers are available in single piece, hinged and slip-on types with or without welding process.

Adjustable bow heights and full ranges of sizes ranging from 4-1/2" to 20" can satisfy almost all cementing projects in oil and gas cementing constructions.

The starting force testing and restoring force testing of our bow spring centralizers are performed in accordance with API 10D Standards.
