4-1/2"~20" Straight/Spiral Vane Solid Centralizer
Straight/Spiral Vane Solid Centralizer
› Available in straight or spiral vane types
› It is used in areas where a good primary cementing job is required, including deviated and horizontal wells, liner overlaps and shoe joints.
› Spiral vane is developed in response to the need for better cementing and can provide optimum flow area in high deviated and horizontal well.
› Reduced flow area between the spiral blades produces a vortex motion of the fluids for more fluid velocity with direction.
› Made of cast steel, which is high tensile and solid for shock and impact resistance.
› 360 degree overlapping solid vanes provide maximum wall contact and fluid swirl.
› Powder coating treatment provide excellent corrosion and rust resistance performance.
› Vane ends are beveled 30 degree relative to the casing centerline to provide excellent lead into restrictions and reduced drag when running in the wellbore. Besides, it keeps running forces at a minimum.
› Wide vanes distribute load from the casing string into the wellbore without gouging.
› Standard size is 4-1/2" to 20". Any special sizes or combinations can be customized on request.
› Available in with or without set screws for eliminating of stop collars.
