Cementing Accesories
Cement Basket (solid or hinged)
UZTEL cement baskets protect weak formations from excessive hydrostatic pressure exerted by the weight of the cement column. They are normaly installed on the casing string above the weak formations, but they are also used in stage-cementing or in cementing the annulus from the surface.
Cement baskets should be installed over stop collars to facilitate pipe reciprocation.
Cement baskets can be disassambled for shipping and space economy.
UZTEL hinged baskets can be installed on upset pipe sizes ranging from 4 ½ to 20 inches; special sizes are available upon request.

Stop Collars
UZTEL stop collars limit the movement of mechanical cementing products on the pipe and are manufactured to withstand high 
axial forces.
Available sizes for 4 ½ “ to 20 “ casing.
Special sizes available upon request.
JSH Stop Collars
This hinged stop collar has an internal groove into which a spiral locking pin is driven, firmly wedging the collar into position around the casing. The JSH collar is used on both upset and non-upset casing and provides maximum annular clearance.
Available sizes for 4 ½ “ to 20 “ casing.
Special sizes available upon request. 
CT-IA and IA Scratchers
UZTEL's CT-IA (close-tolerance, internal-abrading), and IA (internal-abrading) scratchers remove excessive wall cake and improve the cement bond between the casing and porous formations while reinforcing the cement column. Hinged design makes the scratchers easy to install. The inclined external bristles abrade the wellbore during running and reciprocation. The CT-IA short, rigid, internal bristles remove mill scale, coatings and other materials as the scratchers travel along the pipe between stop collars. The CT-IA scratchers feature large fluid bypass slots. Both the CT-IA and the IA, the scratchers have double-coiled bristles for bending durability.
Available sizes for 4 ½ “ to 20 “ casing.
Special sizes available upon request.
