Solid Rigid Centralizers – Cast Steel & Cast Aluminum

Solid rigid centralizers are one series of casing centralizers, which are integral part of cementing processing. They are built out of solid steel bar or cast iron with a fixed blade height and are sized to fit a specific casing or hole size.

It is available in steel or aluminum materials with spiral or straight blade body construction in standard and customized sizes to match different casing sizes and wellbore conditions. Roller centralizers are also available for customers' requirements.

Solid rigid centralizers are available in deviated or horizontal wells. But it is rarely selected in the vertical wells because of the smaller diameter than the wellbore.

Straight/Spiral Vane Solid Centralizer

A red color straight vane and three spiral vane solid rigid centralizer SRC-01-SV

Straight/Spiral Vane Solid Centralizer

  • Available in straight or spiral vane types
  • It is used in areas where a good primary cementing job is required, including deviated and horizontal wells, liner overlaps and shoe joints.
  • Spiral vane is developed in response to the need for better cementing and can provide optimum flow area in high deviated and horizontal well.
  • Reduced flow area between the spiral blades produces a vortex motion of the fluids for more fluid velocity with direction.
  • Made of cast steel, which is high tensile and solid for shock and impact resistance.
  • 360 degree overlapping solid vanes provide maximum wall contact and fluid swirl.
  • Powder coating treatment provide excellent corrosion and rust resistance performance.
  • Vane ends are beveled 30 degree relative to the casing centerline to provide excellent lead into restrictions and reduced drag when running in the wellbore. Besides, it keeps running forces at a minimum.
  • Wide vanes distribute load from the casing string into the wellbore without gouging.
  • Standard size is 4-1/2" to 20". Any special sizes or combinations can be customized on request.
  • Available in with or without set screws for eliminating of stop collars.

Straight/Spiral Roller Solid Centralizer

A red color straight and a spiral roller solid rigid centralizers SRC-02-SR

Straight/Spiral Roller Solid Centralizers

  • Fully heat treated rollers are fixed on every straight or spiral blades/vanes.
  • Better capacity than the straight/spiral vanes solid centralizers because of rigid body and rolling friction between the roller and inside of well or casing.
  • Made of cast steel, which is high tensile and solid for shock and impact resistance.
  • Roller/wheeled centralizers are mainly used for high deviated wells and horizontal wells to centralize casing.
  • Can remove wellbore cake and improve mud replacement efficiency.
  • Provide superior wear resistance and remain functional throughout the life of the well and can aid in casing/tubing retrieval.
  • Smaller roller-contact area reduces the risk of differential sticking and maintains standoff when running casing through open holes.
  • Rollers are crimped in place, eliminating the welding process, while ensuring the rollers cannot bread free and fall intot he wellbore.
  • Available in sizes 4-1/2" to 20".

Straight/Spiral Vane Aluminum Solid Centralizer

A piece of straight and a spiral vane aluminum solid centralizer on white background. SRC-03-SVA

Straight/Spiral Vane Aluminum Solid Centralizer

  • Made of high tensile, solid, cast aluminum for shock, impact and corrosion resistance.
  • Used in areas where a good primary cementing job is required, including deviated and horizontal wells, liner overlaps and shoe joints.
  • Suitable for either cased or open hole.
  • Spiral vanes fully overlap to give 100% wellbore coverage and increase annular turbulence to improve wellbore cleanout.
  • Vane ends are beveled 30 degree relative to the casing centerline to provide excellent lead into restrictions and reduced drag when running in the wellbore. Besides, it keeps running forces at a minimum.
  • Wide vanes distribute load from the casing string into the wellbore without gouging.
  • Standard size is 4-1/2" to 20". Any special sizes or combinations can be customized on request.

Slip-On Stand Off Band Centralizer

SRC-04-SO
  • The centralizer is made of stamped steel.
  • It is designed for vertical well configurations where lateral loads are at a minimum.
  • It is designed to provide a positive stand off the casing for both cased and open holes.
  • The stand off centralizer is required where close tolerance between the casing and the hole is being encountered.
  • It allows for reciprocation and rotation during cementing and can be installed between set screw stop collar.
  • Available in all sizes ranging from 4-1/2" to 20" and any special sizes or combinations are available on request.

Slip-On Welded Straight Cage Rigid Centralizer

Slip-On Welded Straight Cage Rigid Centralizer

SRC-05-SPW
  • It is designed for high deviated horizontal well where casing centralization is the main consideration.
  • Rolled alloy steel ars are welded to the one piece roll formed end collar under required temperature.
  • Provide superior toughness over other material.
  • Its insured positive standoff, maximum flow, maximum well bore stabilization, maximum holding strength and decreased drag.
  • It is directly installed on pipe by slipping on and with or without setscrews for elimination of stop collar.
  • All centralizers are painted or coated with polyester powder.
  • Available in all sizes ranging from 4-1/2" to 20" and any special sizes and combinations are available on request.

Spiral Vane Hydro-Forming Centralizer

Red spiral vane solid rigid centralizer. SRC-06-SPW

Spiral Vane Hydro-Forming Centralizer

SRC-06-SPW
  • It is used in the casing string to facilitate improved cementing.
  • It provides superior strength and rigidity capable of withstanding dynamic downhole loads while maintaining standoff under large side forces without crushing.
  • It provides positive centralization for cementing in vertical and deviated wells.
  • Centralizers located up-hole from the pit will condition the well bore during drilling.
  • Spiral blade design enhances circulation, hole cleaning and cementing.
  • The hard facing on blades provide excellent wear resistance while drilling in abrasive formations.
