Product Description

Spiral Blades Configurations Thermoplastic Centraliser /Composite Centralizer/Nylon Casing Centraliser


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. 
 
Description: 
 
- 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 
 
 The tools come complete with integral metal anti-swage rings inset into each end. Available in Spiral (22-25°) or Passive (5°) angle bladed configurations. Both blade styles are water-melon shaped to pass through windows, washouts and tight spots. 

The Passive (5°) angle  has been developed and tested in conjunction with one of the industry's leading Horizontal Open Hole Gravel Packing solutions providers, to ensure that during Gravel Pack Sand Pumping Operations the sand can be pumped past the centraliser without the danger of early screen out.
