Product Description

API 10D Pipe Made Single Piece Bow Spring Centralizer

Designed specifically for positive centralization of casing pipe for highly deviated and horizontal wells. These are fitted with specially designed Boat shaped vanes for low friction to reduce drag force while running the pipe. Vane design also resists high side loads.

One piece roll formed collars & spirally oriented vanes welded under controlled conditions for maximum rigidity and minimum distortion.

Steel construction provides superior toughness over other materials and alloys. Spiral orientation creates vortex flow to optimize mud displacement and minimizes pressure drop across the spiralizer. Vanes can be selected to meet any hole dia from a choice of seven Boat profile depths.

Slip on spiralizers are provided for direct installation on pipe by slipping on and can be provided with compatible stop collars slightly tapered on outside surface positioned by set screws. They are available in all sizes ranging from 31/2" to 133/8". They undergo a special process of rust prevention before painting .

Heavy duty Spiralizers are specially designed for highly deviated horizontal wells and for use with liner hangers.
The heavy steel construction is highly effective as compared to other alloys and its construction provides maximum standoff. These Centralizers provide low coefficient of friction to reduce drag forces while running in pipe thus optimizing mud displacement and minimizing pressure drop across the Centralizer. They have a high wear resistance and resist high side loads. These are available in all sizes ranging from 31/2" to 20".

 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.

 
Rigid centralizer

Rigid casing centralizer is used in deviated wells and horizontal wells. There are several blades on the rigid centralizer that can keep casing from contacting the wellbore wall

Roller rigid centralizer which is most suitable for highly deviated wells and horizontal wells has two or three rollers in each blade. It can change slipping friction to rolling friction, so the Roller rigid centralizer greatly reduces the friction between casing and wellbore wall and let casing go to desired position smoothly
 

Cast aluminum centralizer:
The smooth spiral 360 overlap solid vane design of centralizers provide max wall contact will not damage wellhead equipment, has high impact and shock resistance comand fluid swirl. The 30slope from the body to the height of the vane will eliminate scraping, or digging into the formation.
The solid cast aluminum centralizers bine with high tensile and yield strengths
