PA4B

The SPIR-O-LIZER® ‘Passive Angled Four Blade’ is a die-cast, zinc alloy, solid blade centralizer that has been specifically designed for sand control/gravel pack applications. A four bladed unit complete with reduced blade angle to maximize flow area, minimize back pressure and potential pack-off.

Features/Benefits

  • Positive standoff protects screen jackets from damage while running in through the wellbore and greatly assists with hole clean up
  • Fluid by-pass has been maximized to eliminate pack-off during clean up and gravel pumping operations
  • Manufactured from zinc alloy providing:
    • High strength - allowing thinner wall sections giving maximum flow-by
    • Exceptional wear resistance - maximum standoff
    • Low coefficient friction - reducing torque & drag
    • Withstands temperatures up to 400° F
  • Maximum torque & drag reduction

Options

  • Centralizer placement/T&D analysis available
  • Split unit available
