An Overview of Bow Spring Centralizer Types

Below are the some types of Bow Spring Centralizer

Hinged Non Welded Bow Spring Centralizer: DIC Oil Tools is a Hinged Non Welded Bow Spring centralizes Manufacturer. Designed to centralize in less demanding well-bore applications. Commonly used to position the casing in the center of the wellbore in both vertical and deviated wells. DIC, centralizers can decrease gas channeling by reducing the movement of the pipe before the cement sets it. These bow centralizers also provide a semi-rigid casing standoff. Made under state of Engineering Techniques, and a rugged quality system. Size Ranging: 4½ to 24.”

Features:   

  • Characteristics are combined with a simple field assembly
  • Made of high-strength steel for maximum structural strength.

Hinged Welded Bow Spring Centralizer: Used where the chances of corrosion, contamination are more, used for water well. Also used where the chances of corrosion and contamination are more. They can used for water well. These centralizers connect a very high restoring force with a very low starting force. Made from 100% stainless steel along with stainless steel nails. Heat Treatment plant to achieve uniform hardness all over and good spring action. Made of special alloy steel. This is available in sizes ranging from 4-1/2” to 20”2.

Features

  • DIC Welded Bow Spring Centralizer can centralize the casing pipe in vertical, deviation and, horizontal wells.
  • These bow spring centralizers provide an excellent standoff, because allows for an efficient mud and cement displacement.

Slip on Welded Bow Spring Centralizer: This is almost the same as Hinged Welded Bow Spring Centralizers. Specially designed with roll-formed peripheral ridges which provide extra rigidity. Used for direct installation on the pipe by slipping on, and also used with set screw for the elimination of stop collar. Sizes ranging from 3 1/2” to 20”. DIC Slip on Welded Bow Spring Centralizer Manufactured as per customer requirement. Generally shipped in half assembled condition for the economy in shipping. Combined with an easy field installation on the pipe rack.

Features:

  • Good centralize in less challenging wells
  • These can improve the cleaning action of drilling fluids.

Bow Spring Centralizer Manufactured as per customer requirement

Hinged Non Welded Bow Spring Turbolizer Centralizer: Made of Heat Treated spring steel. Processed under rigid conditions. It contains the Right and Left-hand combination. Bows are fitted on a uniquely designed self-locking End Collar. These undergo a special Iron phosphate coating process to prevent them from Rust. The spring action of blades makes them pliable, which minimizes damage while moving downhole. Shipped in half assembled condition for the economy in shipping and storage costs.

Features:

  • High-quality spring steel grade
  • Suitable for passing through the wellbore

Hinged Welded Bow Spring Turbolizer Centralizer: It induces a spiral flow pattern in the slurry and which helps in increasing displacement efficiency. Made up of Heat Treated Spring steel, which is processed under rigid conditions. Springs are emphatically welded to the End Collar under needed temperature. Condition with extra-low Hydrogen coated Electrodes. This is available in sizes ranging from 3½” to 20”. Also be available as per customer requirement. This is ideal for a deviated and horizontal well.

Features:

  • These are supplies with a stop collar and hinge pin
  • Other Special Features are built-in stop device on leading end collar

Hinged Non-Welded Stainless Steel Centralizer: Also Used where the chances of corrosion and contamination are more, and also used for water well. Made from 100% stainless steel along with stainless steel nails. We have also available a combination of bows from a choice of seven standard bow heights for optimum starting and restoring force. Also used for anti-corrosion treatment. Designed with self-locking action that is easy to assemble, time-saving and having a strong grip

Features:

  • Longer Functional Life
  • Made using quality grade stainless steel

Longer Functional Life

Slip on Welded Bow Spring Turbolizer: DIC, Slip on Welded Bow Spring Turbolizer General design, features, and characteristics are the same as Hinged Welded Turbolizer. Specially designed with roll-formed peripheral ridges which provide them extra rigidity. DIC are broadly known in the market for directly installing on the pipe by slipping on. Used for direct installation on the pipe by slipping on and then it can be provided with Setscrew for the elimination of Stop Collar. Turbolizer Device helps in improving the cleaning action of Drilling Fluids. 

Features:

  • These improve the cleaning action of Drilling Fluids
  • especial Iron Phosphate coating procedure to Prevent Rust and insures stockings in the open for a long time

Rotating Welded Centralizer: Rotating Welded Centralizer is specially designed to meet or even exceed the API 10 D specifications to have high restoring force. Used with a rotating liner in highly deviated well conditions. Our centralizer improves the cleaning action of drilling fluids, and distributes the cement slurry into wellbore irregularities, and reduces channeling. They are allowing free rotation of the pipe for maximum displacement efficiency. This Centralizer is sizes ranging from 3½” to 20”and we have available as per customer requirement.

Features:

  • providing excellent downhole durability and performance
  • All Size tested, and Validated to API 10D requirements.

Hinged Non Welded Positive Bow Centralizer: Designed with flat bottom U profiles of different Bases. Hinged Non Welded Positive Bow Centralizer are made up of 1/4” or 6 mm less than the inside diameter of the hole size in which centralizer is to be worked. Ten special U sizes Bow can be configured to any hole dia, and Made up of high-quality steel for consistent characteristics.

Features:

  • Centralizer provides almost 100% Standoff therefore run inside a cased hole
  • Easy to assemble, save time, and have a strong grip.

High-quality spring steel grade

Hinged Semi-Rigid Non Welded Bow Spring Centralizer: This can withstand high lateral load encountered. Made of premium quality alloy steel processed under a rigid heat treatment plant. If you compared to other spring bow centralizers this device contains a high stand-off because of high Restoring force. These Spring Centralizer features of Double-Crested profile permits compression because which facilitates movement through tight spots and doglegs. Sizes are available as per customer requirements.

Features:

  • Various heights and sizes are also available, and which make it suitable for most applications.
  • Made of premium quality Alloy Steel processed under rigid Heat Treatment Plant.

Slip on Semi-Rigid Welded Bow Spring Centralizer: These have the same design and characteristics as Hinged Welded Centralizers. They can directly install into the pipe and are provided with set screw-style stop collars to extend the holding force. Passed through a special Iron Phosphate coating process to prevent Rust. Then coated with special Polyester Powder. We have also available a variety of bows configured from a choice of four standard bow heights.

Features:

  • Provide a very high restoring force in combination.

Centralizer Sub: Made to allow centering devices to run into wellbores. Where standard tolerance centralizers are less due to stop collars not capable of withstanding drag and fit limitations. Supplied in almost any casing size, grade, or thread. Used in challenging wellbore configurations. DIC Centralizer Sub is made to allow centering devices to run into wellbores. Which standard tolerance centralizers is less due to stop collars not being capable of withstanding drag and fit limitations.

Features:

Can remove mud and cement in very tight forbearance wellbores
