Hinged Welded Double Bow Spring Centralizer

Eneroil’s semi-rigid centralizers attain higher stand-off, when compared to other bow spring centralizers, because of their higher restoring forces.
The spring characteristics of its double-crested profile permit compression to facilitate movement through tight spots and dog legs.
A high restoring force combined with a low starting force is achieved with all bow heights.
Hinge locking pins are made of high-strength steel for maximum structural strength.
Is able to centralise the casing pipe in vertical, deviated and horizontal wells.
Installation on the casing pipe is very convenient since it simply requires the placement of the two assembled halves on the pipe and the insertion of the pin in the end collar hinge.
Eneroil offers a wide range of bow heights and shapes enabling the customer to make an optimum choice matching their requirements.
These centralizers are designed to be installed between stop collars or casing collars. Eneroil does not recommend installing semi-rigid centralizers over a stop collar.

Welded hinged semi-rigid bow spring centralizers are available in sizes 2 ⅞" to 30”
Special sizes or combination can be made available on request
