Ductile Iron Rigid Spiral Casing Centralizer
The ductile iron centralizer is a rigid centralizing component. It is mainly used for oil-gas well cementing to centralize casing. It is also applied for pipe string positioning in hydrological, geothermal drilling and underground pipeline projects to reduce sucker rod-tubing wear. It is not suitable for high-curvature horizontal wells, highly corrosive or ultra-high-temperature deep wells. It has straight-vane and spiral-vane designs, and the spiral-vane type works better for cement slurry agitation.
