Product Description
Compared to conventional elastic centralizers, dual-bow elastic centralizers can increase the supporting force on the wellbore wall during cementing and reduce friction during string running.
| Product name | Non-Welded Bow Spring Centralizers |
| Material | Steel |
| Size | 4-1/2″×6″-13-3/8″×17-1/2″ |
| Applications | l Tubing or casing applications l Horizontal and directional wells with high side-load conditions l Vertical wellbores where low running force and high standoff are required. |
Features, Advantages, and Benefits
l 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.
l The double-crested design can withstand high lateral loads for reliable performance in directional and horizontal wells.
l double-crested bows provide better standoff for more effective mud removal, which enhances the primary cement job and zonal isolation.
l Bow configurations are available in various heights and sizes suitable for most applications.
l Easy-Installing and cost-saving in shipping.
