API 10D Spec Standard Single Piece Centralizer
This integral one-piece bow spring centralizer is a high-end centralization product. The
centralizers are built to gauge to offer easier, RIH, maximize standoff, and maximize the cement job. The UROS range of centralizers are built mostly for passing through close tolerance situations and then opening back up into under reamed holed sections, or washed out sections, while still providing quality stand-off performance. Bow spring sections are based on a straight bladed principle, but are curved in both axial and tangential directions. This cross curvature conforms to the borehole wall, while the axial curvature changes proportionally as it encounters different loads. As the loads increase, the surface contact area also increases, reducing the load per square unit of area. This helps avoid compression and shear failure of the formation surface.
Features
? One-piece integral unit combined with zero start and running force.
? High standoff ratio (+85%) combined with high restoring force.
? Straight blade to achieve maximum slide effect.
? Designed to compress fully in tight spots.
? Reduces both torque and drag.
? Made to gauge.
? Sizes range from 4 1/2"to 20".

We provided single piece centralizer is highly admired by our respected clients owing to its features like flexibility, operating fluency and many more. The offered piece centralizer is used to centralize casing during the cementing stage of oil wells. This provided piece centralizer is manufactured using the superb quality raw material and the latest technology
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.
Welded Slip On Spring Bow Centralizer has the same Operation, General Design, Features and Characteristics as the Hinged Welded Centralizers. Collars are specially designed with roll formed peripheral ridges which provide extra rigidity. Slips On Centralizers are provided for direct installation on pipe by slipping on and can be providing with SetScrew for elimination of Stop collar. They are shipped in assembled condition only.
Both types Centralizers are available with combination of Bows configure from choice of seven standard Bow height for optimum Starting and Restoring Force. These centralizers undergo a special Iron Phosphate coating process to prevent from Rust then coated with special Polyester Powder they are available in all sizes ranging from 4 ½ " to 20 ".
