Non-welded Hinged Semi Rigid Centralizer

Saigao's non-welded hinged semi-rigid bow spring centralizers ensure high efficiency in casing jobs on deviated and horizontal wells. Combining the features of a standard bow spring centralizer with those of a rigid centralizer, these centralizers provide a very high restoring force in combination with a very low starting force for centralising the casing pipe in vertical, deviated, and horizontal wells.

A non-welded design features the self-locking of lips for holding bows to end collars. Bows of special alloy steel are hot-formed and then tempered for optimum strength, resilience, and uniformity. The bows can also be configured for any hole diameter with a choice of various standard bow heights for optimum starting and restoring forces.

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 GROUPoffers 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.

Options of Non-welded Hinged Semi-rigid Bow Spring Centralizer

Non-welded hinged semi-rigid bow spring centralizers are available in the sizes 2 ⅞" to 30"
