A Single Piece Centralizer made with one-piece welded at one side. These premium quality bows have a high restoring force and an uniform hardness all over. Designed for direct installation on the pipe by slipping on. Because there are no welds these centralizers have high tensile strength and a high shock absorption and impact value.
Hinged Non Welded
Positive Rigid Bow Spring Centralizer
Uniquely designed with a flat bottom U profile of different depths. These centralizers significantly reduce frictional drag while being used in deviated holes. They can provide almost 100% Stand Off when running inside a cased hole.
Hinged Non Welded
Bow Spring Turbolizers
They share all the characteristics of a regular centralizers when it comes to starting force. The main difference are the deflector blades, which are fitted on the Bow Springs. These blades are specially made of Heat Treated spring steel.
Hinged Welded
Bow Spring Turbolizers
These Turbolizers induce a spiral flow pattern in the slurry to increase displacement efficiency. The deflector blades are made of Heat Treated spring steel and are processed under rigid conditions per API 10D specifications. Ideal for deviated and horizontal wells.
Hinged Welded
Drill Pipe Centralizer
Runs freely into difficult wellbores while providing an excellent standoff. The bows are heat treated in a special furnace, which gives it a peculiar ‘Bow Spring’ action. The heat treated bows provide the best centralization as well as help in a faster running of casing.
Hinged Non Welded
Semi Rigid Bow Spring Centralizer
Has the ability to withstand high lateral load encountered. They ensure high efficiency in casing jobs on deviated and horizontal wells. These centralizers combine the features of a standard spring bow with the features of a Rigid Centralizer. The high restoring force, high stand off with low running force makes them ideal for deviated and horizontal wells where load on springs is maximum.
Slip On Welded
Bow Spring Turbolizers
These Turbolizers share the same characteristics as the Hinged Welded Turbolizers, but are specially designed with roll formed peripheral ridged to provide extra rigidity. Made for direct installation on the pipe by slipping on, and can be delivered with Setscrew to eliminate Stop Collar.
Slip On Welded
Semi Rigid Bow Spring Centralizers
Sharing the same design and operational features as the Hinged Welded Centralizers, they can be directly installed onto pipe. The collars have an innovative design with roll formed peripheral ridges that provide extra rigidity.
Hinged Welded
Semi Rigid Bow Spring Centralizer
These Semi Rigid Centralizers ensure a high efficiency in casing. Welded Centralizers have more restoring force compared to Non Welded Centralizers. These Semi Rigid Centralizers are equipped with a double crested Bow Spring that is strongly welded to the End Collar under required temperature and conditions with extra low Hydrogen coated Electrodes, which assure ultimate strength and uniformity in every weld. The integral hinge that is folded on the inside stay intact even under extreme stress.

Solid body Centralizers
Zinc Straight Blade
Solid Rigid Centralizer
The Zinc Straight Blade Solid Rigid Centralizer provides the right feature for getting a good primary cementing job with maximum wellbore stand off. They provide ultimate drag and torque reduction with maximum fluid bypass.
Carbon Steel Spiral Blade
Solid Rigid Centralizer
Designed the same as a Welded Spiral Blade Solid Rigid Centralizer. They are all stored and painted or coated with polyester powder and come in a wide range of sizes. Custom sizes are also possible on request.
Roller Centralizer
Low Torque Type
The Low Torque Roller Centralizers are designed to run in inclined or horizontal sections. The rollers’ envelope outside diameter is kept slightly larger than the centralizer fins’ envelope outer diameter, while the rollers’ envelope inside diameter is kept slightly larger than the fins’ envelope inner diameter. When casing equipped with a Roller Centralizer runs into the deviated or horizontal hole, the sliding friction between the casing and the borehole is converted into rolling friction.
Roller Centralizer
Low Drag Type
A complete mechanical friction-reduction solution for extended-reach wells. It reduces torque, drag, casing wear, tool-joint wear and differential sticking while also improving directional control, ROP and hole cleaning. All the rollers’ are arranged in a horizontal direction to efficiently reduce dragging force.
Slip On Heavy Duty
Straight Spirolizer
The steel construction provides superior toughness over other materials, while electrodes assure ultimate strength and uniformity in every weld. Vanes can be selected to meet any hole diameter from a choice of seven boat profile depths.
Aluminium Spiral Blade
Solid Rigid Centralizer
Developed in response to the need for better cementing in high deviated and horizontal wells. They provide optimum flow and the fins overlap the entire 360-degree open hole circumference. Its reduced flow area between the spiral provides and creates vortex motion to increase fluid velocity with direction. Even without rotation, the relived angle fins induce turbulent flow for improved cutting and filter cake removal.
Aluminium Straight Blade
Solid Rigid Centralizer
Used in areas where a good primary cementing job is required, including deviated and horizontal wells, liner overlaps and shoe joints. Suitable for either cased or open hole wellbores. Made of high tensile, solid, cast aluminium for shock, impact and corrosion resistance. The Vane ends are beveled 30 degrees relative to casing centerline to provide excellent lead into restrictions, and reduced drag when running into hole.
Slip On Welded
Heavy Duty Positive Spirolizer
Designed for extra heavy load in highly deviated horizontal wells and for use with Liner Hangers. The heavy steel construction is highly effective and the wide symmetrical Spiral fins are welded to the one piece rolled formed Sleeve under the required temperature and conditions with extra low Hydrogen coated Electrodes, which assure ultimate strength in every weld.
Steel Spiral Blade
Solid Rigid Centralizer
Constructed of one-piece high strength corrosion resistant steel. These centralizers have high graded castings followed with surface finishing on the CNC Lathe. The rigid inspection after makes a high quality Solid Rigid Centralizer.
Zinc Spiral Blade
Solid Rigid Centralizer
Designed in such a way that it provides efficient functionality and are checked on a regular basis, used in different industrial applications. The Zinc Spiral Blade Solid Rigid Centralizers are simple and convenient, extensively used for rough and fine polishing of metallurgical specimens. The gentle flow from the body to the heigh of the vane will eliminate scraping, gouging or digging into the formation and consequently reducing balling between the blades.
Slip On Welded
Positive Spirolizer
The Slip On Welded Positive Spirolizer is specially designed for highly deviated or horizontal wells and ideal for use with Liner hangers. The steel construction ensures extra strength and superior toughness. The boat shaped spiral fins drag forces while running pipe and glide smoothly in the low side of horizontal bore holes. The Wide symmetrical fins are beveled on both ends to have a lower coefficient of friction and ease casing movement in either direction.
Slip On
Stand Off Band
The Stand Off Band is designed to provide a positive stand off the casing for both cased and open holes. The angled fins provide an increased turbulent flow. The Stand Off Band is required where close tolerance between the casing and the hole is being encountered. The design of the Stand Off Band allows for reciprocation and rotation during cementing and it can be installed between Set Screw Stop Collar.
