Slip on Single Piece Bow Spring Centralizer For Casing
This One-Piece Centralizer has ultra-high strength without any weak point. The centralizer provides high restoring forces while keeping starting and running forces at or near zero lbf. This minimizes drags during casing running and maximizes standoff during cementing operations.
Hinged Non-Weld Bow Spring Centralizer For Oil Tools
Non-welded bow-spring centralizers centralize casing or tubing in the wellbore during running and cementing operations. The high-quality, spring steel bows are attached to hinged end collars with locking tabs. The elasticity of the centralizer gives it a capability to be run through tight spots. Non-welded bow spring centralizers are available in several bow heights and sizes to ensure optimum restoring force and provide in a variety of bow configurations for special applications. Applications 1、Tubing or casing applications 2、Vertical and deviated wells 3、Wells where rotation capabilities are not required 4、Cased and open holes Features, Advantages, and Benefits 1、The non-welded bow spring centralizers are available in sizes 4-1/2" to 20". 2、High quality bows made of special alloy steel with uniform hardness provide optimum performance. 3、Interlocking design between the end collars and bow springs makes a reliable downhole performance. 4.Bow configurations are available in various heights and sizes suitable for most applications. 5、All the centralizers have been tested and validated to meet API Specification 10D. 6、Easy-Installing and cost-saving in shipping.
Double Bows Hinged Spring Semi-rigid Centralizer For Oil Equipment
Non-welded semi rigid centralizers are specifically designed to increase restoring forces and reduce drag during running and cementing operations compared to conventional bow spring centralizers. Applications 1、Tubing or casing applications 2、Horizontal and directional wells with high side-load conditions 3、Vertical wellbores where low running force and high standoff are required Features, Advantages, and Benefits 1、The design of double-crested bows produces centralizers that have starting forces far below API 10D along with very low drag forces, allows the centralizer to compress in order to get through tight spots and severe doglegs that may be present down-hole. 2、Compared to conventional bow spring centralizers, double-crested bows provide better standoff for more effective mud removal, which enhances the primary cement job and zonal isolation. 3、The double-crested design can withstand high lateral loads for reliable performance in directional and horizontal wells. 4、Interlocking design between the end collars and bow springs makes a reliable downhole performance. 5、Bow configurations are available in various heights and sizes suitable for most applications. 6、Easy-Installing and cost-saving in shipping.
Hinged Welded Bow Spring Centralizer For Cementing Tools
Welded bow-spring centralizers provide excellent downhole durability and performance. These centralizers feature heat-treated, spring-steel bows that are welded to rigid end collars. Applications 1、Cased and open holes 2、Vertical or slightly deviated wells 3、Under reamed and washed-out wells Features, Advantages, and Benefits 1、The high-quality, spring-steel bows are heat treated to optimize standoff in gauge holes, under reamed holes, and washed-out sections. 2、Various bow shapes and heights are available to provide optimum restoring forces for most well requirements.
