The roller centralizer is with rigid body and straight or spiral blade.  The centralizer body is processed by casting, the rollers is alloy steel and then heat treatment. Duo to the low friction feature and roller, it is easy to run between roller and inside of casing. The roller centralizer is used in horzontal or deviated well to centre casing. This kinds of centralizer can remove the wellbore stone and make the mud flow easily. The roller provides high wear resistance and has long life for centralizer. Our centralizer coating is powder baking in high temperature. The roller centralizer sizes are from 4-1/2inch to 20inch, any special sizes are available according requirement.

Stage Cementing Collar Hydraulic Type  (Two Stage) Stage Cementing Collar Hydraulic Type (two stage) Hydraulic Stage Cementing Collar is a field-proven stage tool that meets the challenges of cementing holes at any angle with a hydraulically opened port system. It is specifically designed for horizontal sections / formations, the multistage cementing tool can be placed anywhere in the casing string. It is PDC-drillable and field-adjustable shear pins system. When the first-stage shutoff plug lands on the shutoff baffle, increased internal casing pressure hydraulically opens the stage tool, enabling circulation and then second-stage cement to pass though the ports into the annulus above the tool. The closing plug when released, wipes the casing ID clean of cement before bumping on a closing seat. Increased pressure shifts the closing seat downward, releasing locking lugs and closing the tool. A snap ring locks the sleeve in position, ensuring the stage tool remains locked. With 12 years’ export experiences, our stage collar , stage cementing collar hydraulic type, cementing basket , linger hanger  and cementing plug  has been welcomed in international markets.

Reamer Shoe Reamer Shoe is designed specifically to be installed on Casing or Liner and Screen where operators have concerns about potentially difficult wellbore conditions such as, swelling shale's, ledges and washed out areas of wellbore, post drilling and prior to running casing. The aluminum eccentric guide nose climbs ledges and negotiates obstructions while the cutting structure reams out tight spots or obstruction in the wellbore. Compatible with all casing and liner hanger assemblies, our Reamer Shoe provides highly effective protection- against unexpected or anticipated casing and liner running problems, and has been specifically designed for potentially difficult wellbore conditions such as swelling shales, ledges and washed out areas of wellbore. The high strength profiled alloy nose will anchor even in uncured cement to facilitate ease of drill out. The aluminum eccentric nose is easily drilled with both PDC and Rock bits. The chip breaker holes in the nose assembly are designed to create small aluminum chips to avoid “bird nesting” on the bit. Benefits to customers include improved drill out times without compromising the reaming capabilities, a reduction in NPT and increased opportunities to reach TD.
