Product Name: Straight Vane Plastic/ Casing Composite Centralizer Model NO.: Cast Aluminium Type: Centralizer Material: Plastic Structure: Roller Centralizer Type: Rigid Surface Treatment: Polishing Certification: API Material1: Rigid/Nylon/Cast Aluminum/Idler Wheel Height: 650 Weight: 13 Bow Number: 6 Type1: Bow Type2: Slip on Color: as Requested Application: Oil Product Trademark: zhngshi Transport Package: Wf or Wc Specification: API Origin: China HS Code: 7302 Product Description Product name: Casing centralizerProduct classification: Bow-spring centralizer, Rigid roller centralizer, Cast aluminum centralizerProduct overview: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 centralizer1. These Centralizers are designed for High Restoring Force and Low Starting Force for centralizing the casing pipe in a Vertical, Horizontal and Deviated well2. Premium quality Bows are made of special alloy steel and hot formed in totally controlled heat treatment plant to achieve the uniform hardness all over3. 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 centralizerRigid 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 wallRoller 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 smoothlyCast 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 strengthsNo.TypeInside diameter (mm)Height (mm)Total height (mm)Largest diameter (mm)15 "*12-1/4"128-13110569033025 "*20"128-13110572053535-1/2 "*7"142-1485565021545-1/2 "*8-1/2"142-1485565022556 "*8-1/2"156-1585565023567 "*8-1/2"181-1865565023577 "*9-5/8"181-1865565025587-5/8 "*9-5/8"197-2015565027599-5/8 "*12-1/4"250-255556503301013-3/8 "*17-1/2"342-34755650450115-1/2 "*8-1/2"142-148110650225127 "*9-5/8"181-186110650255137 "*8-1/2"181-186110650235145 "*6-1/2"128-131110650175157-5/8 "*9-1/2"196-2001106502501610-3/4 "*12-1/4"274-276110650330175 "*6-1/4"130-132110650170189-5/8 "*12-1/4"250-2551106503301913-3/8 "*17-1/2"342-347110650450205-1/2 "*8-1/2"142-14855650225No.SpecificationBowTypeID(mm)Length(mm)Max.O.D(mm)BowSpring15-1/2"*8-1/2"I,II142-148650±50225±5527"*8-1/2"I,II181-186650±50235±5639-5/8"*12-1/4"I,II250-255650±50330±58410-3/4"*12-1/4"I,II274-276650±50330±59513-3/8"*17-1/2"I,II342-347650±50450±511620"*26"I,II510±1600±50660±512
