00SO Exceptional Performance in Demanding Wells
High-strength 00SO slip-on stop collars are engineered to deliver exceptional performance in the most demanding well conditions.
00SO Slip on Stop Collar
Stop-collar performance is critical to ensuring centralizers remain in their intended position during casing running, rotation, reciprocation and cementing operations.
Centek designs and manufactures a comprehensive range of slip-on and hinged stop collars for different casing grades, annular clearances, installation methods and holding-force requirements. The range extends from economical products for conventional well sections to heavy-duty and ultra-heavy-duty solutions for demanding casing programs.
Slip-on stop collars provide a compact, high-strength method of securing centralizers to the casing. Set-screw configurations incorporate anti-vibration retention and are designed to provide dependable holding performance while minimizing the risk of damage to the tubular.
Hinged stop collars provide an alternative where a slip-on product cannot be installed. They can be fitted around the casing at the pipe rack or rig site and are available with set-screw, hinge-pin and spiral-nail configurations.
The range includes the 0SO, 00SO, HDSO and UHD slip-on stop collars together with the 00SH, HDSH and HSN hinged designs. Each product is developed to complement specific Centek centralizer ranges and well conditions.
Selecting the correct stop collar requires consideration of casing grade, surface condition, centralizer type, expected axial loading and the available annular clearance. Centek’s Product Service Experts can recommend the appropriate product and installation procedure for each application.
