SPIRASLIDER 

• Designed especially for highly deviated or horizontal wells.
• The steel construction ensures extra strength and superior toughness.
• Boat shaped vanes for low friction to reduce drag force while running the pipe.
• Vanes are welded on single piece roll formed collars under controlled conditions for maximum rigidity and minimum distortions.
• Provided for direct installation on the pipe by slipping on and can be provided with compatible Stop Collars beveled from one side positioned by set screw. 

       Available Size: 4-1/2" to 13-3/8".

WELDED ROTATING CENTRALIZER 

We are highly instrumental in offering a wide and comprehensive range of Welded Rotating Centralizers. 

• Designed for meeting the requirements for centralizers that are utilized with a rotating liner in highly deviated conditions. 
• High restoring force for optimum standoff
• Low moving force to minimize drag
• Allow free rotation of the pipe for maximum displacement efficiency
• Over stop collar design minimizes moving forces while reciprocating

Available Size:  4-1/2"x 6" and 7" x 8-1/2".
