Slip-on Welded Semi-Rigid Bow Centralizers

Eneroil’s semi-rigid centralizers attain higher stand-off, when compared to other bow spring centralizers, because of their higher restoring forces.
Able to centralise the casing pipe in vertical, deviated, and horizontal wells.
End collars are of widened-design for greater frame strength and to prevent the bows from hitting the casing.
The compatibility of the bows with various end collar sizes reduces inventory requirements and provides tremendous flexibility of casing and hole size combinations.
Bows can be configured for any hole diameter with a choice of six standard bow heights for optimum starting and restoring forces.
Bow springs are of high quality alloy steel, bent to shape and heat treated under controlled temperature / time cycles for consistent spring characteristics.
Hinge locking pins are made of high-strength steel for maximum structural strength.
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.
Its high performance characteristics are combined with an easy field installation on pipe rack.

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