Slip-On Welded Positive Spirolizer
The COS Slip-On Welded Positive Spirolizer is specifically engineered for highly deviated and horizontal wells, where smooth casing movement and reliable centralization are critical. It is particularly well-suited for use with liner hanger applications.
Built from premium-grade steel, the Spirolizer delivers superior toughness and strength compared to other materials, ensuring reliable performance in demanding wellbore conditions.
Design & Features
- Spiral Fin Geometry – Boat-shaped spiral fins minimize drag forces and glide smoothly along the low side of horizontal boreholes.
- Beveled Fin Edges – Wide, symmetrical fins are smoothly beveled on both ends, reducing friction and easing casing movement in either direction.
- High Load Resistance – The fin design withstands high side loads, providing durability and reliable centralization.
- Welded End Collars – Spirally oriented fins are precision welded to a one-piece rolled-formed end collar using extra low-hydrogen coated electrodes, ensuring uniformity, ultimate strength, and structural integrity.
- Steel Construction – Provides superior impact resistance and long-lasting toughness under extreme wellbore conditions.
Benefits
- Optimized for horizontal and deviated wells.
- Reduced drag and improved casing movement efficiency.
- Durable welded structure for maximum reliability.
- Smooth fluid bypass with minimized turbulence.
Sizes Available
- Standard: 2 7/8″ to 30″
- Special/custom sizes available on request.
