Product Description

Product Description
Casing centralizer description:

Premium quality Bows are made of special alloy steel and hot formed in totally controlled heat treatment plant to achieve the uniform hardness all over.
Spec and performance index of bow spring casing centralizer meet API Spec 10D.                                                     

The woven centralizer is connected by pin when in use, the unfolded centralizer can be stacked flatly for convenient storage and transportation.

 

Casing centralizer 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.

The integrated structure can increase the strength load, and the composite material can withstand high temperature

Rib plate structure can significantly reduce the friction resistance when entering the pipe string. The ribbed structure can glide smoothly at the bottom of the wellbore and pass the obstacle smoothly

The shape of the rib plate can enhance the swirl flow, reduce the pressure drop, and achieve the ideal slurry replacement effect

The composite material has extremely high hardness and durability, and can maintain the integrity of the tool under extremely high temperature at the bottom of the well

Lightweight structure, more convenient and safe to install and use

The roller centralizer is a rigid body, and the centralizer bar is a straight bar or a spiral bar

The centralizing blocks are equipped with rollers, which are made of alloy steel after heat treatment

Roller centralizer is mainly used for centralizing casing in high-angle wells or horizontal wells

Roller centralizer can unclog the borehole obstruction, improve the efficiency of replacement

Low torque and low friction resistance can realize rotating operation and lifting and lowering construction, greatly improving the slurry replacement effect and cementing operation quality
