Saigao's spiral vane thermoplastic centralizers with swage metal ring are manufactured using engineered material with a swaged mild-steel ring both on the top and the bottom end which are designed for the maximum durability, drag, and friction downhole achievable in a centralizer. Additionally, these centralizers have lower friction factors, a rotational torque reduction, and increased abrasion resistance for a maximum stand-off. Spiral vanes help enhance hole-cleaning by using a maximised flow-by area. The vanes overlap the entire 360° open-hole circumference, which creates a vortex motion to increase fluid velocity with direction. Even without rotation, the vanes are able to induce turbulent flows for an improved cutting and filter cake removal.
Saigao's spiral vane thermoplastic centralizers with swage metal rings provide high impact resistance as well as chemical and high temperature resistance.
The extra length of the vanes provides maximum centralisation, a high stand-off, and increased annular turbulence.
Its high performance characteristics are combined with a quick and effortless installation.
