Slip On Solid Body Spiral Blade Rigid Composite Centralizer with Metal Rings

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.

Features

• The tool is made from a high temperature high-pressure injection moulded polymer.
• It is available in BOS21 standard grade polymer composite for most low friction requirements as well as BOS22 self lubricating polymer composite for low friction water based mud applications.
• The tools are available in Spiral (22-25°) or Passive (5°) angle bladed. configurations. Both blade styles are watermelon shaped to pass through casing and multi-lateral windows, washouts and tight spots.

This centralizer is the option for ultimate friction reduction, offering field proven lower friction co-efficient leading to superior drag and rotational torque reduction. It extends the current well construction boundaries on ERD and highly deviated wells.
