Non-welded Hinged Semi-rigid Bow Spring Centralizer

Performance Features of Non-welded Hinged Semi-rigid Bow Spring Centralizer

• Saigao's semi-rigid centralizers attain higher stand-off, when compared to other bow spring centralizers, because of their higher restoring force.

• Able to withstand high lateral loads.

• 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.

• 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.

• Saigao 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. Saigao does not recommend installing semi-rigid centralizers over a stop collar.
