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.
