 Slip
on Positive Welded Spiralizer |
|
| |
 |
Designed specifically for positive centralization of casing
pipe for highly deviated and horizontal wells. These are
fitted with specially designed Boat shaped vanes for low
friction to reduce drag force while running the pipe.
Vane design also resists high side loads.
One piece roll formed collars & spirally oriented
vanes welded under controlled conditions for maximum rigidity
and minimum distortion.
Steel construction provides superior toughness over other
materials and alloys. Spiral orientation creates vortex
flow to optimize mud displacement and minimizes pressure
drop across the spiralizer. Vanes can be selected to meet
any hole dia from a choice of seven Boat profile depths.
Slip on spiralizers are provided for direct installation
on pipe by slipping on and can be provided with compatible
stop collars slightly tapered on outside surface positioned
by set screws. They are available in all sizes ranging
from 31/2"
to 133/8".
They undergo a special process of rust prevention before
painting . |
