3 Section Structure Spiral Glider Centralizer , Red Pipe Centralisers

Product Description

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 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.

Spiral Glider Centralizer Types

Bow Spring Casing Centralizer:

single pipece centralizer, non welded centralizer, welded centralizer

Rigid Casing Centralizer:

steel centralizer, aluminum centralizer, composite centralizer (both straight vane and spiral vane are available)

Semi-rigid Casing Centralizer:

. Produced and tested to meet API 10D specification .

. Robust single piece design, suitable for onshore installation

. Tiny starting forces and restoring forces are much great than API standard .

. Flexible design reduces running forces through any cased hole restrictions, has an extremely low co-efficient    of friction, speed the process of running casing liners to final depth.
