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.
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.
