Product Description

integral  single piece bow spring centralizer 
 
The latest centralisers are manufactured from a single piece of heat-treated steel giving a hardened and tempered surface that results in greatly reduced torque and drag losses. These centralisers offer high fatigue strength for axial forces and radial side loads on bows during tubular rotation.   

Our specially designed Single Piece Centralizer, eliminate the risk of loose part or welding failure as it is all made from one single piece using state of the art manufacturing process and material. Run in close tolerance applications mainly on liners.
 
Non Weld Bow Centralizers are designed and developed for use in the most demanding conditions and meet or exceed the API 10-D specification.
 
 
 Non Weld Bow Centralizers have high restoring force combined with low starting force for centralizing the casing pipe in vertical, deviated and horizontal wells. These centralizers reduce the effect of channeling by improving the cement flow thus resulting in uniform thickness between the wellbore and casing.
 
The Centralizers are able to minimize gas channeling by reducing the movement of pipe before the cement sets in.
 
The Single piece centralizer can be installed with 2 stop rings, 1 internal stop ring or casing couplings. The blades, top and bottoms rings are made of one piece to ensure the centralizer s integrity during rig operations. 
 
 
The Single piece centralizers are available in sizes 4½" to 20" . (Any special sizes or combination can available on request).
