Straight Vane Aluminum Rigid Centralizer Fixed - DAV03
SledgeHammer's Straight Vane Aluminum Rigid Centralizer Fixed features are same as DAV02 except screws between vanes. The Straight Vane Aluminum Rigid Centralizer Fixed should be used in areas where a good primary cementing job is required, including deviated and horizontal wells, liner overlaps, and shoe joints. They are suitable for either cased or open hole."DAV03" are made of high tensile, solid, cast aluminum, for shock, impact, and corrosion resistance same as "DAV02".
Vane ends are beveled 30 degrees relative to casing centerline to provide excellent lead into restrictions, and reduced drag when running into hole. Wide vanes distribute load from the casing string into the wellbore without gouging. If rotation is required, install without setscrews and position between stop-collars, or between stop-collar and casing collar. It will work same as "DAV02". If rotation is not required than just tighten up screw as shown on the picture.
Available in 3 1/2" to 20" sizes + any special sizes or combination can available on request.
