Non Weld Semi Rigid Bow Centralizers (S 29) |
|
Eneroil’s Steelfabs brand Non Weld Semi Rigid Bow Centralizers are available in the size range 4½" to 20", this device ensures high efficiency in casing jobs on deviated and horizontal wells. Combining the features of a standard spring bow and rigid centralizer, it has bows manufactured from alloy steel tempered for exact hardness and a non- weld design to eliminate brittle spots.
The spring characteristics of its double crested profile permit compression to facilitate movement through tight spots and dog legs. Compared to other Spring Bow Centralizers this device attains higher stand-off because of its higher restoring force. |
