Hinged Welded Bow Spring Turbolizer
COS’s Hinged Welded Bow Spring Turbolizer is specifically designed to enhance cement displacement and mud removal by inducing a spiral flow pattern in the cement slurry. Featuring heat-treated deflector blades mounted on high-strength bow springs, this tool ensures improved fluid turbulence, reduced channeling, and a more reliable cement bond in challenging well conditions.
Key Benefits
- Creates turbulent slurry flow → improves cement placement and displacement efficiency
- Suitable for deviated and horizontal wells where fluid circulation is critical
- Flexible metal fins minimize downhole damage while maintaining turbulence
- Higher restoring force than non-welded designs → better casing standoff
- Corrosion-resistant finish for extended service life
Features
- Deflector blades (right & left-hand combinations) fitted on bow springs for induced turbulence
- Bow springs welded to end collars with extra low-hydrogen electrodes for superior strength
- Integral hinge withstands extreme stresses without failure
- Reinforced end collars with stamped ribs for added structural toughness
- Built-in stop device on the leading collar prevents over-travel
- Special iron phosphate coating + polyester powder finish to prevent rust
- Shipped in half-assembled condition for reduced shipping and storage costs
- Available in 2 7/8” to 30” (custom sizes on request)
Applications
- Primary cementing in deviated, extended reach, or horizontal wells
- Wells requiring improved mud removal and cement bonding
- Situations where flow turbulence is necessary to reduce channeling
