Composite Solid Rigid Centralizer for Downhole
Product Description
API Composite Solid Rigid Centralizer
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

Our composite centralizers provide the following benefits:
Reduce total well construction costs - eliminate the need for expensive casing couplings
Enables casing or screen deployment in longer reach wells - industry leading low friction factors reduce torque and drag, enabling the user to reach total depth
Zero corrosion - totally non-metallic material removes the contamination risk to carbon or expensive hi-chrome content steel tubulars and completion equipment
Low wear and material loss - low friction factors and advanced material formulations result in low wear
High impact and side load resistance - longer lasting
Light weight - the size to weight ratio is significantly lower than metallic centralizers which reduces freight and handling costs
Specific OD's can be accommodated - composite material can be machined down to meet requirements.
