Oilwell Spiral Blade Roller Type Thermoplastic Casing Centralizer

Spiral Blade Composite Thermoplastic Solid Centralizer  with Set Screws

Our advanced thermoplastic  centralizers are light weight, highly durable and exhibit ultra low friction factors. They are made from proprietary composite material formulations  .


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.
