Product Description

  7inch thermoplastic casing centralizer with coating


Composite Casing Centraliser is the ultimate in down-hole centralisation, offering field proven lower friction coefficients leading to superior drag and rotational torque reduction. High abrasion resistant proprietary engineered polymer ensures maximum stand-off at TD. Robust enough to meet the challenges of today's most demanding wells. 
 
Composite Materials: 
- 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
