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.
