China Stoff Solid Spiral Blades Cast Aluminum Casi Cast Aluminium Casing Centralizer Plastic Casing

Stand Off Solid Spiral Blades Cast Aluminum Casing CentralizerThe smooth spiral 360o overlapping solid vane design of the Stand-Off Solid "Spiral blade" Centralizers provide maximum wall contact and annular fluid swirl. The 30° slope of the vane ends reduce drag and aid the casing in reaching TD. This gentle slope from the body to the height of the vane will eliminate scraping, gouging, or digging into the formation and consequently reduce balling between the vanes. Clean vanes allow complete utilization of the spiral centralizer in swirling the fluids, rather than just splashing the fluid.
The solid cast aluminum Stand-Off Centralizers will not damage wellhead equipment, have high impact and shock resistance combined with high tensile and yield strengths, as well as corrosion resistance. Casting not only makes a well designed tough tool, Insulation but reduces manufacturing costs.
