Hinged bow spring centralizers are a traditional and economic centralizers. This kind of centralizers are used in general vertical or slightly deviated wells.
Single Piece Centralizers
The single piece centralizers are available in sizes 4-1/2 ” to 20". Any special sizes or combination can be available on requirement.
Turbulent Spring Centralizers
The spinning disk on the centralizer string work closely with casing to form a whirl channel to improve the efficency of cement slurry displacement
Offset Bow Spring Centralizers
The offset bow offers significant reduction in initial insertion forces as well as substantially reduces running forces through the previous set casing.r
Solid Rigid Centralizers
The 360 degrees oerlapping solid vane provides maximum wall contact and fluid swirl.
Roller Centralizers
Roller Centralizers are available in sizes 4-1/2” to 20”. Any special sizes are available on request.
Composite Centralizers
Made of advanced composite, the onepiece centralizer has a Iow coefficient of friction, it is heat resistant which is highly durable and greatly enhances cementing operations.
Preset Force Centralizers
The centralizer strip can be deformed when passing through the string, it is easy to let casing go through.
Hinged Bolt Type Collar
Hinged Stop Collar is designed to latch on the casing pipe without having to be slipped on at the end of the casing pipe allowing quick and easy installation.
Slip on Stop Collar
This kind of set screw stop collars are recommended for small hole operation. It is used when holding force requirement is very high.
Reciporcating Well Bore Wipers
A continuous, interlocking and overlapping loop of tempered steel wire cable is laced into the hinged collars.
Cement Basket
It is usually mounted on the casing string on the above of the weak stratum structure, but also used during stage cementing and surface cementing.
