Solid Rigid Centralizers
Slip On Welded Positive Spiralizer
Slip On Welded Spiralizer was designed for use in highly deviated horizontal wells and with line hangers. The heavy steel construction is very effective compared to other alloys and its construction provides maximum standoff. The Spiralizers can be directly installed on the pipe and are accompanied by Stop Collars positioned by set screws.
This product has boat shaped spiral fins that reduce drag forces while running in pipe
thus optimising mud displacement and minimising pressure drop. They have resistance to high side loads and are smoothly beveled on both ends to promote a lower coefficient of friction easing casing movement in either direction. The welding of the fins is performed under special conditions with low hydrogen coated electrodes. This ensures optimal strength and uniformity in every weld. In addition, all products under go a special iron phosphate coating process to prevent corrosion and are then coated by a special polyester powder. All products fulfill requirements as per 10 TR5
Available in 4-1/2” to 20” sizes.
Any special sizes or combinations can be made available on request.
Slip On Heavy Duty Welded Positive Spiralizer
Slip On Heavy Duty Welded Positive Spiralizer are specially designed to respond to extra heavy loads in highly deviated horizontal wells and for use with Liner Hangers. The heavy steel construction is highly effective as compared to other alloys. This Spiralizer can be directly installed onto the pipe by slipping it on and is accompanied by compatible Stop Collars beveled from one side positioned by set screws.
This Spiralizer is equipped with hydrodynamic spiral fins that allow optimal mud
displacement and minimal pressure drop across the Centralizer. In addition, they are particularly strong with high wear resistance. The wide symmetrical spiral fins are welded to the sleeve under special temperature conditions using extra low hydrogen coated electrodes and this further assures ultimate strength and uniformity in every weld.
Resistance to corrosion is provided by a special iron phosphate coating process
complemented by a coating of polyester powder. All products fulfill requirements as per 10 TR5
Available in 4-1/2” to 20” sizes.
Any special sizes or combinations can be made available on request.
Slip On Heavy Duty Straight Spiralizer
Slip On Welded Heavy Duty Spiralizer is designed especially for highly deviated and horizontal wells. They are ideal for use with Liner Hangers. The heavy steel construction is highly effective and provides superior toughness over other materials.
Wide symmetrical straight fins are welded to the one piece of rolled formed sleeve under
required temperature and conditions using low hydrogen coated electrodes. This ensures ultimate strength and uniformity in every weld. The fins are designed to provide low coefficient of friction to reduce drag forces while running the pipe.
They create a vortex flow to optimise mud displacement and minimise pressure drop
across the Centralizer. Vanes can be selected to meet any hole diameter from a choice of seven boat profile depths. All products receive a special phosphate coating to prevent corrosion and are then treated with a special polyester powder. All products fulfill requirements as per 10 TR5
Available in 4-1/2” to 20” sizes.
Any special sizes or combinations can be made available on request.
Slip on Stand off Band
Slip On Standoff Band is designed to provide a positive stand off of the casing. It can be used in both cased and open holes and is required in situations where close tolerance between the casing and hole is being encountered. It is particularly effective for liner applications.
The angled fins provide increased turbulent flow and further torque can be achieved by
installing the band between a set screw Stop collar
The product is treated against corrosion using a special phosphate coating followed by polyester coating. All products fulfill requirements as per 10 TR5
Available in 4-1/2” to 20” sizes.
Any special sizes or combinations can be made available on request.
Thermoplastic Centralizer
The use of thermoplastics in centralizer manufacturing has been gaining popularity in recent years due to their high strength-to-weight ratio, chemical resistance, and lower cost compared to metal centralizers. However, their use may be limited in certain wellbore conditions, such as high-temperature environments, where the plastic materials may not be able to withstand the extreme temperatures.
Overall, thermoplastic centralizers offer a lightweight, corrosion-resistant, and cost-effective solution for casing centralization in oil and gas drilling operations. Their design and material selection can be tailored to meet the specific requirements of the wellbore and the drilling operation, making them a versatile option for a wide range of applications. All products fulfill requirements as per 10 TR5
Available in 4-1/2” to 20” sizes.
Any special sizes or combinations can be made available on request.
Aluminum Spiral Vane Solid Rigid Centralizer
Aluminum Spiral Solid 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
Centralizers are also able to withstand high well bore temperature while providing maximum horizontal standoff.
The fins or blades overlap the entire 360-degree open hole circumference and the
reduced flow area between the spirals provides and creates a vortex motion that increases fluid velocity. Another benefit is that the extra length of the fins gives maximum centralization, high stand off and increases annular turbulence while the angle further enhances turbulence and removal of debris from around the casing. Even without rotation, the angled fins still induce turbulent flow for improved cutting and filter cake removal. All products fulfill requirements as per 10 TR5
Available in 4-1/2” to 20” sizes.
Any special sizes or combinations can be made available on request.
