LAXMI Non-Welded Casing Centralizers delivers excellent performance under compressive load and is suitable for standard application where, either no rotation is required or minimizing drag force is not a consideration. These Centralizers are Non-Welded & Hinged-type and are designed to keep all Lip integral with the End Collars. It has a interlocking between the End Collar and Bow, which makes it a strong single unit. Construction of the Centralizers ensures that hinges does not open while casing is being run, regardless of hole direction or irregularities in formations and that the centralizer will provide effective centering down the hole.

These centralizers are not optimized for open hole casing size combinations so they tend to be less expensive than other types.

Available from 4-1/2” size through to 30” casing size.

Welded bow spring centralizers are optimized for specific pipe and hole size combinations, which result in lower drag forces. The welded design provides better performance under tensile loads allow rotation of the string/casing within the centralizer. The lower running force and higher restoring force make it a good choice when operating in washed out and highly inclined sections.

LAXMI welded Casing Centralizers bow design is similar to Non Welded Hinged type Centralizer but in this type of Centralizers bows are welded to the end collar to provide superior strength. The bows are strongly welded to end collars with correct grade electrode to ensure desired performance of centralizer under load.

These Centralizers are available in Slip on and Latch on type configuration. The Latch-on Hinged type also feature integral hinges, which folded inside thereby minimizing collar stretch. Welded bow centralizer can be supplied in straight, spiral and positive configuration. All specification dimensions are same as non - welded Centralizers but have strength exceeding then that of Welded Centralizers.

LAXMI Semi Rigid Double Bow Spring Centralizers bows are designed for higher Restoring force while, keeping Low Starting and Running Force. With Hinged construction and dual contour bow profile, these centralizers allows complete centering in under slight over guage holes ensuring the centering force which can be produced with positive or rigid centralizer.

These Centralizers are used where Casing inside a cased well is lowered. It keeps the casing centered in the cased. It protects previously run cemented casing from shocks and vibrations caused by drilling. The outside diameter of the bows are kept 1/4" smaller then the cased well bore that they are being run into. These include the reduction in drag associated with running pipe in deviated and horizontal wells. These Centralizers are designed to be installed between Stop Collars or free floated on the Casing.

These type of centralizers are available for both Welded & Non Welded makes.

These Centralizers are available in sizes from 5-1/2" through to 20" casing size.

LAXMI Non-Welded Integral Bow centralizer is a single piece slip-on type spring bow casing Centralizer. These centralizers are made from high strength steel which is heat treated and hardned for desired spring action. The integral single piece design enables it to reduce channeling effect by improving the cement flow. This enhances uniformity in cement thickness in well bore and also minimises gas channeling.

These Centralizers have high restoring force with zero starting force & zero running force, And also offer high fatigue strength for axial forces and radial side loads on bows during tubular rotation.

It gives good performance in open hole and in cased hole. This type of Centralizer meets or exceeds API specifiction 10D.

These Centralizers are used to keep the casing in the center of well bore in vertical devited and horizontal wells.

The single piece spring bow Casing Centralizers are available in sizes 41/2" to 13 3/8".

LAXMI Finned Type Rigid Centralizer is a slip-on centralizer consists of straight or spiral hollow steel fins welded to steel collars. The shape of fins are designed such that the drag force is minimal, enabling reciprocations and rotations while running pipe, thus, the centralizers can be glided smoothly in lower side of horizontal boreholes. The fins also have a pre-defined collapse load to yield under stuck pipe conditions. These centralizers have larger flow area which reduces the circulation pressure. These characteristics of Finned Type Rigid Centralizers makes them well suited for highly deviated or horizontal wells.

These centralizers can be used with Liner Hangers slim hole environment & close tolerance drift diameters. They are used in conjunction with stop collars to correctly locate them on the casing.

Finned Centralizer are made in various lengths as per customer requirement.

LAXMI make Solid Spiral Centralizer designed for maximum stand-off between the Casing Pipe, with the well bore through out the 360º contact surface. These Centralizers have been specially designed for heavy deviated, horizontal wells & offers reduced drag in such wells. These may also be used in straight wells. The Solid design allows a fixed Standoff regardless of lateral forces. The smooth overlapping Spirals provides maximum wall contact and greater flow area. These Centralizer provide positive Centralized Standoff and break up Jelled fluid pockets as the Tubulars are run into the hole. By providing the positive Standoff between the Casing & Well bore walls it eliminate narrow and wide sides of Casing where Cement flow tends to avoid the narrow annulus portion. Free rotation installation allow the Solid Centralizer to act as a bearing Surface during rotation or reciprocation with the Tubulars rotating freely thus reducing torque. These Centralizer are highly suitable when a good Cement bond is essential.

Solid Body Rigid centralizers are available in Alloys of Aluminum, Zinc and Steel. Each alloy of material has its own characteristics such as the acid resistance, lightweight handling and anti corrosive properties.

Our Special Aluminum Alloy Solid Body Rigid Centralizer are light weighted and have high tensile strength, High impact strength and shock resistance properties and can effectively work in operational temperatures up to 500º F.

The product is available in Alloy of Aluminum, Zinc and Steel in Size Form 3½” to 13.3/8” Casing. It can be manufactured with straight blade or spiral blade with left or right hand flow.

TURBOLIZERS are similar to straight Casing Centralizer but, with turbulence blades are fitted on each bow. The blade are scientifically shaped into multi direction design to guide the fluid in an out ward spirally direction against the walls of the well holes and around the Casing. Blade also induce turbulence in the cement slurry during cementing operation. Bows of Turbolizer are made of double rolled uniformly heat treated spring steel which make them flexible to minimixe damage while moving down hole.

Turbolizer are available in the same sizes and bow height as straight bow Casing Centralizers.

Laxmi Udyog manufacturers two types of Turbolizers; Single Bow Turbolizer which have one blade on each bow and Double bow Turbolizer which have two blades on each bow. Both blade are oriented in opposite direction.

Turbolizer are available in the same sizes and bow height as straights bow Casing Centralizers. Turbolizer blade are supplied in left hand or right hand direction.

LAXMI Spirolizers are designed for superior strength, rigidity, Toughness and high wear resistance enabling it of supporting large load of instant deviating and horizontal load. These are manufactured from seamless pipe by either embossing blades onto it by a mechanical process or by welding “U” shaped blades on pipe running from top collar to bottom collar.

Slip on Glider Spirolizers can be manufactured in both Straight blades and Spiral blades designs.

Slip on Spirolizer can easily fit on casing by inserting from one end of casing pipe. They are spiral & straight blade type Spirolizers. Spiral blade design are used where hole cleaning and better cement placement with minimum pressure drop is required.

LAXMI Stop Collar are used to limit the travel of Centralizers, Turbolizers, Solid Centralizers on the Casing Pipe, Stop Collars are available in the 4-1/2" to 20" sizes. All Stop Collars have different type of holding devices and accordingly categrised. Stop Collars are bolts and screw type. They are latchon type and slipon type and beveled slipon types stop collars are quick and easy installation and rerist max. holdding force .

LAXMI is manufacturing metal petal & canvas type Basket. Baskets are slip-on and latch on types. Baskets are used to support an upper cement column during cementing operation. They are normally installed between two Stop Collar used in weak formation in well that requires protection from Hydrostatic Pressure generated by the weight of cement column.

Basket Petals are manufactured from high strength spring steel, which allows for strength and flexibility to support long columns of cement during primary cementing operation. The Cement Basket petals are arranged in an over lapping position that allows for maximum fluid passage from below while allowing for retention of the above fluids through the entire operating range of the Cement Basket. Baskets are hinge type so easily install on casing pipe.

This Basket is manufacturing from spring steel bow fitted with Canvas/Rubber.
Canvas is fitted in side of bow with overlapping. This type of Basket is Slip on type & easily installed by sliding it over the pipe and of casing joints. Baskets are available in wide range of casing size (4-1/2" to 20") to hole sizes and it self-centering due to its sturdy spring steel bows. Design is as such Basket have minimizes interference against casing for assisting pipe rotation and reciprocation.

These are constructed to withstand any treatment from the casing rack to the bottom of the well without impairing their effectiveness. The high strength wire fingers and cable loops distintegrate the toughest filter cake and their working diameter enables them to reach into enlarged scale sections to agitate gelled mud and to make possible a complete cement fill.

These consists of a split collar which houses double coiled external and internal bristles. The external bristle system is incliend 20° and is shielded by slight elevations in the collar. The inclination of these bristles reduces the abrasive action when casing is run into the hole. The bristles are placed in a now position relative to the bore hole wall at each change of direction while moving pipe, thus assuring the cleaning of the entire circumference of the casing and the well bore. The internal bristles serve to remove mill scale and other foreign matter from the casing, improving the bounding of cement to the casing.
