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.
If you have any question on casing centralizer, composite centralizer, hinged welded centralizer, aluminum spiral vane solid rigid centralizer and bow spring centralizer etc. We will give the professional answers to you.
1.The non weld bow centralizers combine the highest restoring force with the lowest starting force.
2.High restoring force combined with low starting force is achieved with all bow heights.
3.The Bows of these Centralizers are heat treated in special furnace which gives it a peculiar â??bow springâ?? action.
4.The Heat Treated bows enables these centralizer to provide best centralization as well as help in faster running of casing.
5.The 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.
6.The bows are available in a range to accommodate any well profile.
7.In this type of Centralizers the End Collars have hinges which makes it in two halves.
8.This enables them to be assembled at site.
9.The Hinged non welded bow spring centralizers are available in size 4-1/2" to 20".
10.Their installation on the casing pipe is very convenient.It requires only the placement of the two assembled halves on the pipe and inserting the pin in the end collar hinge.
11.The centralizer when unassembled makes a compact package, reducing the shipping cost.
12.Assembly at site is conveniently done.

Single Straight Turbolizer Turbolizer centralizers have all of the characteristics of regular centralizers as far as starting and restoring forces are concerned. The main difference is that the Turbolizer centralizers have a built-in stop collar and deflector blades. These blades, or fins, deflect the fluid flow in a turbulent and outward directed spiral. If you have any question on casing centralizer, composite centralizer, hinged welded centralizer, aluminum spiral vane solid rigid centralizer and bow spring centralizer etc. We will give the professional answers to you.
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.

Hinged Non-welded Casing Centralizer Product Description Casing centralizer is one of the necessary conventional casing accessories, upon well operationscompletion, the rational use of casing centralizer can play the role of:Reducing lower casing resistance phenomenon, making the casing smoothly down to the design position; Making casing centralizer centered within the well; Reducing the sticking phenomenon to make the annular space hydrostatic pressure balanced; Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality. The reset force of double bow type centralizer is higher than that of single bow centralizer, centering centering performance is better than that of single bow type. Bow-spring centralizer 1.These Centralizers are designed for High Restoring Force and Low Starting Force for centralizing the casing pipe in a Vertical, Horizontal and Deviated well 2.Premium quality Bows are made of special alloy steel and hot formed in totally controlled heat treatment plant to achieve the uniform hardness all over 3.Spec and performance index of bow spring casing centralizer meet API Spec 10D. The woven centralizer is connected by pin when in use, the unfolded centralizer can be stacked flatly for convenient storage and transportation. Rigid roller centralizer Rigid casing centralizer is used in deviated wells and horizontal wells. There are several blades on the rigid roller centralizerthat can keep casing from contacting the wellbore wall Roller rigid centralizer which is most suitable for highly deviated wells and horizontal wells has two or three rollers in each blade. It can change slipping friction to rolling friction, so the Roller rigid centralizer greatly reduces the friction between casing and wellbore wall and let casing go to desired position smoothly. Cast aluminum centralizer: The smooth spiral 360 overlap solid vane design of centralizers provide max wall contact will not damage wellhead equipment, has high impact and shock resistance comand fluid swirl. The 30slope from the body to the height of the vane will eliminate scraping, or digging into the formation. The solid cast aluminum centralizers bine with high tensile and yield strengths
Rotating Centralizers Rotating centralizers were developed in response to industry requirements for centralizers that could be used with a rotating liner in highly deviated conditions. These centralizers offer the following features: a) High restoring force for optimum standoff b) Low moving force to minimize drag c) Allow free rotation of the pipe for maximum displacement efficiency d) Over stop collar design minimizes moving forces while reciprocating e) Meet or exceed API Specification 10D requirements If you have any question on casing centralizer, composite centralizer, hinged welded centralizer, aluminum spiral vane solid rigid centralizer and bow spring centralizer etc. We will give the professional answers to you.
Single Piece Centralizer Single Piece Bow Spring centralizer is constructed from one piece ensuring high restoring force, uniform hardness and shock absorption. The advantage of the single piece centralizer is that its smooth corner radius reduces friction ensuring that fluids can flow more easily without obstruction.
