Puyangzhongshi API Certificated Alloy Spiral Vane Coated Aluminium Casing Centralizer

Coated aluminum alloy helical blade casing centralizers are machined from high-strength, corrosion-resistant cast aluminum. They can be used with corrosion resistant alloy bushings to avoid the effects of electrical corrosion on the bushing. This type of centralizer has helical blades, which are used to increase the annular turbulence, so as to achieve the effect of cleaning the wellbore. Mainly used for horizontal wells and extended reach wells with low friction coefficient.

Centralizer Features
  • Application:in deviated and horizontal wells, liner overlaps, and shoe joints.
  • The design of the vanes keeps running forces at a minimum
  • Vane ends are beveled 30 degrees relative to casing centralizer to provide excellent lead into restrictions and reduced drag when running into hole.
  • Wide vanes distribute load from the casing string into the well bore without gouging.
  • Suitable for either cased or open hole.
