Product Description
API 10D Slip On Single Piece Bow Spring Casing Centralizer/   Slip On Integral Casing Centralizer 


Our leading products are casing bow spring centralizers,casing rigid centralizers,float collars&shoes,cementing plugs,cement heads,cementing baskets,stage cementing tool and so on. They are mainly supplied to Central Asia, Southeast Asia, Africa and Middle East ,America and many other countries.
Zhongshi Group has been the Tier One internet service provider of Sinopec. We passed ISO9001 quality management system certification and got approved to use API monograms on its oil machineries. So far, we have attained API 5CT certificate, API 10D certificate.

Casing centralizer is one of the necessary conventional casing accessories, upon well operations completion, the rational use of casing centralizer can play the role of:
 
 Reducing lower casing resistance phenomenon, making the casing smoothly down to the design position;
 
 Making casing centralizer centered within the well;
 
 Reducing the sticking phenomenon to make the annular space hydrostatic pressure balanced;
 
 Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality.
  
The reset force of double bow type centralizer is higher than that of single bow centralizer, centering centering performance is better than that of single bow type.

Slip on Welded Single Piece Bow Spring Casing Centralizer is made one piece welded at one side. Premium quality Bows have high restoring force uniform hardness all over. Slip on centralizers are provided for direct installation pipe by slipping on. It has High tensile strength, high shock absorption value and impact value.
In welded centralizers, welding can never be as smooth as the single piece centralizer. Welding always be little overlapped or little exposed which cause friction to fluid while running in the hole but single piece centralizer have smooth corner radius which allow better fluid by pass and have low friction.
 
This centralizer undergoes a special Iron Phosphate coating process to prevent it from rust and coated with special Polyester Powder. It is shipped in assembled condition only. These are available in all sizes ranging from 4½" to 20". Any special sizes or combination can available on request. 
 
API 10D Single Piece Bow Spring Casing Centralizer

The Single Piece Bow Spring Casing Centralizer is newly designed integrated steel flexible Centralizer used to centralize casing during the cementing stage of oil wells. Fully integrated (SLIP-ON) centralizers are manufactured in any diameter and as per customer requirements.
The blades, top and bottoms rings are made of one piece to ensure the centralizer s integrity during rig operations.

The specifications comply with API Spec 10D for starting compression, running down hole and expansion force.

These centralizers offer high fatigue strength for axial forces and radial side loads on bows during tubular rotation.

More flexibility as comparison to other spring bow centralizer.

Features:
1. Starting and restoring force confirm to API Standard.
2. More flexibility as comparison to other spring bow centralizer
3. Greater centering efficiency
4. Higher Stand Off.
5. 360° wall coverage for increased load bearing area.
Available Size: 4-1/2" to 13-3/8".

The starting force and the reset force are both in accordance with the API standards;
Convenient Installation;
The displacement efficiency is improved more effectively with a spinning disk.

Bow spring centralizer
 
 1. These Centralizers are designed for High Restoring Force and Low Starting Force for centralizing the casing pipe in a Vertical, Horizontal and Deviated well
 2. 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

3. 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.
