3/4/2014, · The effectiveness of this type of ,centralizer, is heavily dependent on the ,restoring force,. When the casing is heavy and/or the wellbore is highly deviated, they may not support the casing very well. For example, on a riser tieback casing string, a helically buckled casing could create a side ,force, of 50,000 to 100,000 lbf (222 to 445 kN), well beyond the capabilities of the spring-bow ,centralizer,.

As the bow OD is typically very close to hole size, the centralizer has very low starting and drag forces. The double profile of the bow results in much higher restoring forces than conventional bow-springs. Bows are made from alloy steel, heat-treated and tempered. Utilizes Davis-Lynch patented interlocking bow attachment to end collars.

The shape and stiffness of the bows determine the restoring force, which is defined as the resistance force when a bow is compressed by 1/3 of its uncompressed height. The effectiveness of this type of centralizer is heavily dependent on the restoring force.
