1.Description:
Casing centralizer can be applied directly to casing to form stabilizers for cementing with casing or liner in both straight and directional wells, Usually bow centralizer is used for straight oilwells, rigid centralizer is used for directional oilwell.
Almost 13 years experience of designing, manufacturing and continual improvement of our rigid centralizers for casing cementing, we provides non-welded bow spring centralizers, which are designed and manufactured as per API spec.10 D.
The popular styles available are non-welded single bow spring centralizer, and double -bow spring centralizer,slip on welded centralizer, rigid centralizer, straight bow centralizer with high reliable quality.
2. Featrues:
1,Our newest design has features making them ideal for both tubing and casing applications:
2,The non-weld design eliminates any weak spots.
3,Tapered pin hold the bows and hinges in the collars
4,High-quality, super-strengthen spring-steel bows and especialy designed collar hinges provide reliable downhole performance.
5,The whole casing centralizer is made without any rivet and no welding.
6,The whole casing centralizer is composed of 3 parts, the spring, the hinges and tapered pin.
7,Easy for installation and transport
8,Conform to API 10D standard
