Casing Centralizer :

A metal strip shaped like a hunting bow and attached to a tool or to the outside of casing. Bowspring centralizers are used to keep casing in the center of a well bore or casing ("centralized") prior to and during a cement job.

A device fitted with a hinged collar and bow springs to keep the casing or liner in the center of the well bore to help ensure efficient placement of acement sheath around the casing string. If casing strings are cemented off-center, there is a high risk that a channel of drilling fluid or

contaminated cement will be left where the casing contacts the formation, creating an imperfect seal.

Pipe Centralizers Characters

1) Bow springs made of spring steel which has been heat teated and hardened tempered to ensure proper and consistent spring characteristics.

2) End collar hinges are folded toward inside. This way will minimize the collar stretch taht tends to occur when centralizers encounter tapers, commonly found in certain type of pipe connections.

3)A reinforcing rib stamped into the end collar. This way will strengthen and preserve it's round configuration during transport.

4)Several different spring bow heights that are available to accommodate most of casing-to-hole configuration.

5)Centralizers with built-in stop devices as well as those uncommon sizes are available based on request.

Produced and tested to meet API 10D specification .

. Robust single piece design, suitable for onshore installation

.Tiny starting forces and restoring forces are much great than API standard .

. Flexible design reduces running forces through any cased hole restrictions, has an extremely low co-efficient of friction, speed the process of running casing liners to final depth.
