Aluminum Spiral Vane Solid Rigid Centralizer
Aluminum Spiral Solid Casing Centralizers were developed in response to the need for better cementing in deviated and horizontal wells. The unique design ensures optimal flow area and is strong and resistant to impact, These Casing Centralizers are also able to withstand high well bore temperature while providing maximum horizontal standoff.
Solid vane straight blade centralizers are designed to provide fixed casing standoff, regardless of lateral load. This positive standoff helps ensure even distribution of cement around the well casing.
The spiral centralizer with a 360 overlapping solid vane to provide maximum wellbore contact and maximum wellbore fluid swirl. This centralizer is recommended to be used on shoe joints, through production zones, liner overlaps, and other areas where a good cement bond is essential. The recommended spacing through productive zones is every 20 ft, using the left- and right-hand spiral design in every other sequence.

Composite Centralizer
Composite centralizer is used during running and cementing operations to centralizer casing.
Made of advanced composite, the one-piece centralizer has a low co-efficient of friction, it is heat resistant and highly durable which greatly enhances cementing operations.
Vane Roller Composite Casing Centralizer consists of rigid body, on which machined spiral blades.
are made of advanced composite that has low coefficiency of friction, it is heat resistant and high durable, fully heat treated rollers fixed on each spiral blades.
of rigid body and rolling friction between the rollers and inside of well or casing.
capability of the Casing roller Centralizer is better than others of all. Casing Roller/Wheeled composite centralizers are mainly used for big high Roller, high deviated wells and horizontal wells, to centre casings.
Roller Composite Centralizers can also remove wellbore cake and improve mud replacement efficiency etc.
Composite Centralizers provide superior wear resistance and have been proven to remain functional throughout the life of the well and can aid in casing/tubing retrieval.
inside diameter fits over the casing through the complete API tolerance range, providing excellent rotational performance in mud.
running casing through open hole, the system’s smaller roller-contact area reduces the risk of differential sticking and maintains standoff .
roller/axle relationship ensures that axle shear stresses remain within elastic limits, preventing permanent deformation.
are crimped in place, eliminating the welding process, while ensuring the rollers cannot break free and fall into the wellbore.
system’s high-quality construction materials improve high-pressure/high-temperature capabilities.
Composite Centralizers are available in sizes 4-1/2" to 20".
special sizes are available on request.

Bow Spring Centralizer
Hinged non welded bow spring casing centralizer is a simple, low-cost bow-spring design which can provide complete centralization in vertical or slightly deviated wells as the bow springs are slightly larger than the wellbore.
non weld bow centralizers combine the highest restoring force with the lowest starting force.
restoring force combined with low starting force is achieved with all bow heights.
Bows of these Centralizers are heat treated in special furnace which gives it a peculiar ‘bow spring’ action.
Heat Treated bows enables these centralizer to provide best centralization as well as help in faster running of casing.
steel of these bows is a "special" made by combination or different metals to provide one of the best tensile strength as well as the "spring back" bow spring action.
bows are available in a range to accommodate any well profile.
this type of Centralizers the End Collars have hinges which makes it in two halves.
enables them to be assembled at site.
Hinged non welded bow spring centralizers are available in size 4-1/2" to 20".
installation on the casing pipe is very requires only the placement of the two assembled halves on the pipe and inserting the pin in the end collar hinge.
1 centralizer when unassembled makes a compact package, reducing the shipping cost.
at site is conveniently done.

Hinged Welded Centralizer
Hinged Welded Spring Bow Centralizers are high quality welded products, which meet or exceed API 10D specifications. They are designed for high restoring forces combined with low starting forces essential for centralizing casing pipes. They are manufactured and heat-treated under controlled temperature and time cycles ensuring that the Bow Springs are strongly welded to the End Collar. This ensures minimum distortion and maximum rigidity and integral hinges folded on the inside stay intact even under extreme stress. In addition, the End Collars are designed with a reinforcing rib stamped into the End Collar to ensure maximum strength.

Non Weld Positive Centralizer
Non Weld Positive Casing Centralizer are uniquely designed with flat bottom U profile of different depths. The Centralizers significantly reduce frictional drag while being used in deviated holes. They provide almost 100% Stand Off when run inside a cased hole. They are supplied 1/4" or 6 mm less than the inside diameter of the hole size in which Centralizer is to be run. This design eliminates weak (brittle) spots passage. U profile bow design permits maximum fluid passage.
End Collars are designed with self-locking action, which are easy to assemble, time saver and have strong grip. The Ten special U sizes Bows can be configured to any hole dia. These Bows with extended profile prevent them from hitting against casing collars. Bows are of high quality steel for consistent characteristics. These centralizers undergo a special Iron Phosphate coating process to prevent from Rust then coated with special Polyester Powder. These can be shipped in half assembled condition for economy in shipping and storage costs. They are available in all sizes ranging from 4 1/2" to 20" sizes.

Spiral vane solid rigid centralizer
Spiral vane solid rigid centralizer is specially designed to minimize unwanted removal of well cake and to run the casing easily. It is ideal for highly deviated or horizontal wells. In other words, it is absolutely appropriate for Liner Hanger. Solid rigid centralizer is fabricated from supreme quality material steel construction which ensures that extra strength and superior toughness for standoff performance in at affordable price to our customers.
These centralizers are made shock resistance and with optimum tensile and yield strength.
Both the types of solid rigid centralizer are available here: ‘Straight Blade' and‘Spiral'. By running on the casing OD, they are used to centralize the casing.
This casing is to be cemented in the wellbore. This also improves the bonding of cement in the casing.
These centralizers are designed in such a way that it reduces the amount of friction created between hole and the casing.
This allows the casing to be inserted into the wellbore more easily. Thus, preventing the string of the casing to be stuck.
These centralizers are perfectly tested and are appreciated for their quality standoff and usage before they are dispatched.

Reamer Shoe
Casing 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.
Zhongshi is specialized in produce float equipment, Such as reamer shoe, double valve float collar, etc, Our Casing Float equipment are very popular, if you are interested in our reamer shoes, please contact us as soon as possible.
