Product Description

7'' X 8 1/2'' Slip on Solid Body Spiral Blade Thermoplastic Centralizer 

The composite nylon centralizer is used during running and cementing operations to centralize casing. Made of advanced composite, the one-piece centralizer has a low coefficient of friction, is heat resistant, and is highly durable. The composite material performs reliably even in extreme wellbore conditions. Unlike many plastic centralizers, this centralizer withstands high-impact loading and is highly wear resistant.
 

Description for material : 
- Moulded during high pressure high temperature process 
- Spiral Blades 22-25° and melon shaped 
- Passive Straight Blades 5° and melon shaped 
- Patented Anti-Swage Rings incorporated in each end 
- Generous By-Pass Area provided 
- Numerous Pipe x Hole size configurations available 
- Low Weight 
- Premium Self-Aligning Stop Collars also available  

Features for Casing Rigid Centralizer:

a. Rugged and works well even in deviated wellbores, regardless of the side force.
b. The screws on centralizer can be used as stop collar.
c. High tensile and yield strengths.
d. Available with straight or spiral blades.
e. Helps ensure positive centering in deviated or horizontal holes.
f. Helps prevent differential sticking while running casing.

g. Provide a guaranteed standoff and function as bearings during the pipe rotation.
