Product Description

                                   7'' thermoplastic casing centralizer with metal rings


Thermoplastic Solid Rigid Centralizers are made of special engineered polymer material to meet the various well conditions. This material has high abrasion resistance for maximum stand off and can withstand in wells having temperature up to 400° F temperature.
 

It has low coefficient of friction and ultimate drag forces for performing excellent in deviated and horizontal wells. These centralizers are impact resistive having optimum tensile and yield strength.

 

The Vanes of these centralizers are designed to have improved hole cleaning by filter mud cake removal and enhanced localized turbulence for improved cementing.

 

These centralizers are provided with swage rings at both its ends to enhance strength. Straight or Spiral vanes are available for various requirements. These centralizers are also available with set screws to make it rotation free.

 

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.

 

 

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.
