Bow spring centralizer is deigned for primary cementing, applied in vertical, deviated and horizontal wells where low starting force as high restoring force.

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

It is used to keep casing in the center of wellbore and reduce friction between casing and well bore.

Bow spring centralizer consists of several metal strips shaped like a hunting bow and attached to a tool or to the outside of casing. It is a critical step in quality cementing as the lack of proper centralization can lead to severe cementing problems including lack of zonal isolation and improper casing support.

We ROTATE are dedicated to improve efficiency and safety in field cementing operations, all kinds of casing centralizer can be designed and manufactured according to customer’s requirements.

Available in 4-1/2” to 20” sizes and special sizes are also avaiable.
