Steel Solid Body (Rigid) Casing Centralizer for Downhole IntroductionSolid body (rigid) centralizer is used to casing in the central place of wellbore in cementing process, making align casings through well heads near surface. Rigid centralizer, made from solid steel bar or cast iron with a fixed blade height, is used to fit a specific casing or hole size. Characteristics for Rigid centralizer: 1) Good shock, impact and corrosion resistance; 2) High tensile and yield strengths; 3) Straight or spiral blades are available; 4) Ensure positive centering in deviated or horizontal holes; 5) Prevent differential sticking while running casing; Stamped Centralizer Spiral Stamped centralizer enables optimal mud displacement for vertical, deviated, and horizontal wells. Special rounded blades reduce casing-sliding friction compare with the square blades and are suitable for reciprocation and rotation during cementing. Stop Collar Hinged Bolt Stop Collars Bolt lock mechanism allows for quick and easy installation over casing. Slip on Set Screw Stop Collar Installed with set screws Designed for use where higher holding forces are required. Stainless steel set screws or double-row setscrews are available for applications where more holding force is required or requested. The roller centralizer are designed in rigid body with straight or spiral blades. Rollers provide low drag to get casing, liners, or screens to bottom successfully with reduced rig time and costs. Minimal roller-contact area in open hole applications reduces the risk of differential sticking and provides optimal standoff for increased operational efficiency. Aluminum-Alloy Centralizer The centralizer are made of high strength, corrosion resistant cast aluminum. They can be used with corrosion resistant alloy casing strings to avoid the effects of galvanic corrosion. Their spiral blades increase annular turbulence to improve well bore clean out. It is developed specially for horizontal and extended reach wells with lower coefficient of friction over steel centralizers.Composite Centralizer The Composite centralizer is made of advanced composite that has a low coefficient of friction and is heat resistant and highly durable. This material performs reliably in extreme wellbore conditions. With its smooth, durable, tapered construction.The centralizer can easily pass obstructions in the wellbore, so it is well suited for horizontal applications.
